[Bug c++/15118] New: precompiled headers problem (clalling fdopen: Bad file descriptor)

[Bug c++/15118] New: precompiled headers problem (clalling fdopen: Bad file descriptor)

[gcc-bugzilla at gcc dot gnu dot org]

	When trying to compile some headers g++ says:
	calling fdopen: Bad file descriptor

	See fix for more information.

Environment:
System: Linux hell.hell.gr 2.6.5 #31 Sun Apr 11 18:07:49 EEST 2004 i686 unknown unknown GNU/Linux
Architecture: i686

	
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../gcc-3.4.0/configure --enable-threads=posix --prefix=/usr --enable-languages=c,c++ --enable-shared --with-arch=pentium3 --with-cpu=pentium3 --enable-__cxa_atexit

How-To-Repeat:
	Use this Makefile in qt-3.2.1 include directory:
---
CC=g++ -c -pipe -I/usr/local/postgre/include -I/usr/local/include -I/usr/local/X11/include -I/usr/local/progs/CUPS/include -I/usr/X11R6/include -I/usr/local/ssl/include -fno-exceptions -w -O3 -fprofile-generate -mmmx -ffast-math -fmessage-length=0 -fomit-frame-pointer -D_REENTRANT -fPIC -DQT_SHARED -DQT_NO_DEBUG -DQT_THREAD_SUPPORT -DQT_THREAD_SUPPORT -DQT_NO_NIS -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -DQT_NO_XINERAMA -DQT_BUILTIN_GIF_READER=1 -DQT_NO_STYLE_MAC -DQT_NO_STYLE_AQUA -DQT_NO_STYLE_INTERLACE -DQT_NO_STYLE_WINDOWSXP -DQT_NO_STYLE_COMPACT -I/mnt/extra/usr/local/qt-x11-free-3.2.3/mkspecs/linux-g++ -I. -I../../include/freetype2 -I3rdparty/opentype -I../include -I/usr/X11R6/include -I/usr/X11R6/include -I../src/.moc/release-shared-mt/
gch:
        for fn in *.h ; do \
                if ! test -f $$fn.gch || test $$fn -nt $$fn.gch ; then \
                        echo "${CC} $$fn -o $$fn.gch  || true "; \
                        ${CC} $$fn -o $$fn.gch  || true ; \
                fi ; \
        done

%.h.gch: %.h
        ${CC} $< -o $@

all: gch
---
	This will work on most headers but will give fdopen errors on some of them.

Fix:
	Let's have an example:

g++ -c -pipe -I/usr/local/postgre/include -I/usr/local/include -I/usr/local/X11/include -I/usr/local/progs/CUPS/include -I/usr/X11R6/include -I/usr/local/ssl/include -fno-exceptions -w -O3 -fprofile-generate -mmmx -ffast-math -fmessage-length=0 -fomit-frame-pointer -D_REENTRANT -fPIC -DQT_SHARED -DQT_NO_DEBUG -DQT_THREAD_SUPPORT -DQT_THREAD_SUPPORT -DQT_NO_NIS -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -DQT_NO_XINERAMA -DQT_BUILTIN_GIF_READER=1 -DQT_NO_STYLE_MAC -DQT_NO_STYLE_AQUA -DQT_NO_STYLE_INTERLACE -DQT_NO_STYLE_WINDOWSXP -DQT_NO_STYLE_COMPACT -I/mnt/extra/usr/local/qt-x11-free-3.2.3/mkspecs/linux-g++ -I. -I../../include/freetype2 -I3rdparty/opentype -I../include -I/usr/X11R6/include -I/usr/X11R6/include -I../src/.moc/release-shared-mt/ qftp.h -o qftp.h.gch
In file included from qdatastream.h:42,
                 from qmap.h:44,
                 from qmime.h:43,
                 from qevent.h:45,
                 from qobject.h:45,
                 from qnetworkprotocol.h:45,
                 from qftp.h:44:
qiodevice.h:43:22: calling fdopen: Bad file descriptor

	Next we look at line 43 of qiodevice.h:
#include "qcstring.h"

	Now we remove qcstring.h.gch and it works (!). There are cases where you've to remove more than one .gch files.

	Next we recreate qcstring.h.gch:
g++ -c -pipe -I/usr/local/postgre/include -I/usr/local/include -I/usr/local/X11/include -I/usr/local/progs/CUPS/include -I/usr/X11R6/include -I/usr/local/ssl/include -fno-exceptions -w -O3 -fprofile-generate -mmmx -ffast-math -fmessage-length=0 -fomit-frame-pointer -D_REENTRANT -fPIC -DQT_SHARED -DQT_NO_DEBUG -DQT_THREAD_SUPPORT -DQT_THREAD_SUPPORT -DQT_NO_NIS -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -DQT_NO_XINERAMA -DQT_BUILTIN_GIF_READER=1 -DQT_NO_STYLE_MAC -DQT_NO_STYLE_AQUA -DQT_NO_STYLE_INTERLACE -DQT_NO_STYLE_WINDOWSXP -DQT_NO_STYLE_COMPACT -I/mnt/extra/usr/local/qt-x11-free-3.2.3/mkspecs/linux-g++ -I. -I../../include/freetype2 -I3rdparty/opentype -I../include -I/usr/X11R6/include -I/usr/X11R6/include -I../src/.moc/release-shared-mt/ qcstring.h -o qcstring.h.gch

	And retry the qftp.h:
# g++ -c -pipe -I/usr/local/postgre/include -I/usr/local/include -I/usr/local/X11/include -I/usr/local/progs/CUPS/include -I/usr/X11R6/include -I/usr/local/ssl/include -fno-exceptions -w -O3 -fprofile-generate -mmmx -ffast-math -fmessage-length=0 -fomit-frame-pointer -D_REENTRANT -fPIC -DQT_SHARED -DQT_NO_DEBUG -DQT_THREAD_SUPPORT -DQT_THREAD_SUPPORT -DQT_NO_NIS -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -DQT_NO_XINERAMA -DQT_BUILTIN_GIF_READER=1 -DQT_NO_STYLE_MAC -DQT_NO_STYLE_AQUA -DQT_NO_STYLE_INTERLACE -DQT_NO_STYLE_WINDOWSXP -DQT_NO_STYLE_COMPACT -I/mnt/extra/usr/local/qt-x11-free-3.2.3/mkspecs/linux-g++ -I. -I../../include/freetype2 -I3rdparty/opentype -I../include -I/usr/X11R6/include -I/usr/X11R6/include -I../src/.moc/release-shared-mt/ qftp.h -o qftp.h.gch  
In file included from qdatastream.h:42,
                 from qmap.h:44,
                 from qmime.h:43,
                 from qevent.h:45,
                 from qobject.h:45,
                 from qnetworkprotocol.h:45,
                 from qftp.h:44:
qiodevice.h:43:22: calling fdopen: Bad file descriptor

	(same thing)

	I ran the g++ command under 'strace -f' and I found this:
