[Bug java/21022] New: bootstrap error compiling libgcj with awt support on darwin-ppc

[andreast at gcc dot gnu dot org]

I get the following bus error when I compile libgcj with awt support on darwin:

gnu/java/awt/peer/gtk/GdkFontMetrics.java: In class
'gnu.java.awt.peer.gtk.GdkFontMetrics':
gnu/java/awt/peer/gtk/GdkFontMetrics.java: In constructor '(java.awt.Font)':
gnu/java/awt/peer/gtk/GdkFontMetrics.java:0: internal compiler error: Bus error
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

The backtrace of in gdb of the error looks like this:

I can reproduce this on 4.0.x branch too. Unfortunately the error is not as easy
to reproduce for others. It requires that you have a gtk installation with
shared libgcc. All in all about half a day or more of compilation work.

Anyway.

The error appears since Tom Tromey checked in findirect-dispatch compilation for
the awt-peer sources around 2005-04-05.

The error does also happen on tiger.

Further analysis has showed, if I remove the debug switch -g from the
compilation command, I do not get the bus error.

Note, darwin still uses stabs as preferred dbg format. I was not able to build a
gcc on darwin with dwarf2 as default. Neither was I able to reproduce the
failure on linuxppc -with-stabs.

Andrew Pinski noted on IRC that it might be a java fe bug. 

For me the question is now, how can I continue to debug this error?

The sooner or later (29 of April) the libgcj awt issue will come since then the
new darwin release can really run gtk-awt java based apps.

[Bug java/21022] bootstrap error compiling libgcj with awt support on darwin-ppc

[andreast at gcc dot gnu dot org]

------- Additional Comments From andreast at gcc dot gnu dot org  2005-04-16 20:16 -------
I just built the tree without awt-gtk enabled. The
gnu/java/awt/peer/gtk/GdkFontMetrics.class is built even without gtk enabled.
So, a command line compile of the class to .o is possible and makes the bug
easier to reproduce for others. As Andrew P already mentioned.

On darwin I reproduce the bug this way:

/Volumes/src/gcc/gcc-cvs/objdir/./gcc/jc1
gnu/java/awt/peer/gtk/GdkFontMetrics.class -fhash-synchronization
-fuse-divide-subroutine -fuse-boehm-gc -fnon-call-exceptions
-fkeep-inline-functions -feliminate-unused-debug-symbols -fPIC -quiet -dumpbase
GdkFontMetrics.class -auxbase GdkFontMetrics -g -O2 -Wno-deprecated -version
-fclasspath=
-fbootclasspath=/Volumes/src/gcc/gcc-cvs/objdir/powerpc-apple-darwin7.9.0/libjava:/Volumes/src/gcc/gcc-cvs/gcc/libjava:/Volumes/src/gcc/gcc-cvs/gcc/libjava/external/w3c_dom:/Volumes/src/gcc/gcc-cvs/gcc/libjava/external/sax
-fencoding=UTF-8 -findirect-dispatch -fjni -o /var/tmp//ccA7zDFV.s

It happens on both, 4.0 and 4.1.

Completed a build of HEAD with awt-gtk enabled on darwin7.9.

Thanks!

I run now a build on 4.0, even if we may not get this fix in for 4.0.
