Qt 3.3.3's uic miscompilation by gcc3.4.2/3.4.1/4.0.0-20040914/3.3.5-20040914 ?

[Karel Gardas]

Hello,

I've tried to compile Qt 3.3.3 (thread enabled build) with all these
compilers from subject plus binutils2.14/glibc2.2.5 and found that while
build process compiles Qt designer, Qt's own uic tool crashes with
Segmentation fault:

thinkpad:/tmp/qt-x11-free-3.3.3/tools/designer/plugins/cppeditor$ make
/tmp/qt-x11-free-3.3.3/bin/uic -L /tmp/qt-x11-free-3.3.3/plugins projectsettings.ui -i projectsettings.h -o projectsettings.cpp
make: *** [projectsettings.cpp] Segmentation fault
make: *** Deleting file `projectsettings.cpp'

I've tried both release (O2 compiled) and debug (-O0 -g) builds with the
same results (tested only with 3.4.2). The back trace looks also quite
strange:

0x40d4f98e in ?? ()
(gdb) bt
#0  0x40d4f98e in ?? ()
#1  0x40c2ae53 in exit () from /lib/libc.so.6
#2  0x40c18155 in __libc_start_main () from /lib/libc.so.6
#3  0x080510b1 in _start ()
(gdb)

Also strange thing is that it is possible to compile whole Qt (with
non-segfaulting uic) by using gcc3.3.2.

Do you have any idea how to hunt this issue down to create proper
bugreport? Or do you think this is already reported?

Thanks,

Karel
