Please rerun the above command with -save-temps -v additional options and attach here the resulting .i file. It looks like the code does not play nice with the included headers (for whatever reason, without .i file I cannot tell much), but no matter what even on bad input gcc should never segfault nor generate ICE, so I'd like the testcase so that I can fix it. Created attachment 5015 [details]
Output from -save-temps of gcc
That file (ibex_block.c) has apparently unresolved CVS or RCS conflict in it,
<<<<<<< ibex_block.c
#include <db1/db.h>
=======
>>>>>>> 1.5
That's not valid C obviously, if you fix it, it will work.
I'll work on fixing the ICE though.
Richard Kenner fixed this on Sep, 16th in CVS gcc, I've just verified the backport of this patch into RH gcc fixes it, it will appear in the next gcc rpm package (gcc-2.96-63), which should make it into rawhide first and soon after into gcc errata. |
GCC is segfaulting on a simple compile. I'm trying to compile Evolution from CVS, but I've checked that this compiles elsewhere (on stock RH7 and on RH6.2 with the patches). I've verified my gcc install (rpm -V gcc), and tried this quite a few times. Here's the command line that I'm running to get this crash. gcc -DHAVE_CONFIG_H -I. -I. -I.. -I. -I/usr/lib/glib/include -I/opt/gnome_cvs//include -DUNICODE_USE_SYSTEM_ICONV -DG_LOG_DOMAIN=\"libibex\" -I/usr/lib/glib/include -I/usr/X11R6/include -g -O2 -Wall -Wunused -Wmissing-prototypes -Wmissing-declarations -Wp,-MD,.deps/ibex_block.pp -c ibex_block.c -fPIC -DPIC -o .libs/ibex_block.lo Here's the output that I get back. I'll make a backup of this build tree, so that I can provide additional feedback upon request. BTW, this machine is NOT overclocked or doing any other "bad things" with the hardware. ibex_block.c:246:74: warning: pasting would not give a valid preprocessing token ibex_block.c:4: parse error before `<' In file included from /usr/include/bits/types.h:166, from /usr/include/sys/types.h:31, from /usr/include/db1/db.h:40, from ibex_block.c:6: /usr/include/bits/pthreadtypes.h:48: parse error before `size_t' /usr/include/bits/pthreadtypes.h:48: warning: no semicolon at end of struct or union /usr/include/bits/pthreadtypes.h:51: parse error before `__stacksize' /usr/include/bits/pthreadtypes.h:51: warning: data definition has no type or storage class /usr/include/bits/pthreadtypes.h:52: warning: data definition has no type or storage class In file included from ibex_block.c:6: /usr/include/db1/db.h:76: parse error before `size_t' /usr/include/db1/db.h:76: warning: no semicolon at end of struct or union /usr/include/db1/db.h:77: warning: data definition has no type or storage class /usr/include/db1/db.h:121: parse error before `*' /usr/include/db1/db.h:122: parse error before `*' /usr/include/db1/db.h:123: parse error before `DBT' /usr/include/db1/db.h:124: parse error before `DBT' /usr/include/db1/db.h:142: parse error before `*' /usr/include/db1/db.h:143: warning: no semicolon at end of struct or union /usr/include/db1/db.h:146: parse error before `}' /usr/include/db1/db.h:146: warning: data definition has no type or storage class /usr/include/db1/db.h:158: parse error before `size_t' /usr/include/db1/db.h:171: parse error before `size_t' /usr/include/db1/db.h:171: warning: no semicolon at end of struct or union /usr/include/db1/db.h:174: parse error before `}' /usr/include/db1/db.h:174: warning: data definition has no type or storage class ibex_block.c:6: parse error before `==' In file included from /usr/include/_G_config.h:45, from /usr/include/libio.h:31, from /usr/include/stdio.h:70, from ibex_block.c:9: /usr/include/gconv.h:71: parse error before `size_t' /usr/include/gconv.h:84: parse error before `size_t' /usr/include/gconv.h:93: parse error before `size_t' /usr/include/gconv.h:169: parse error before `size_t' /usr/include/gconv.h:169: warning: no semicolon at end of struct or union /usr/include/gconv.h:172: parse error before `}' /usr/include/gconv.h:172: warning: data definition has no type or storage class In file included from /usr/include/libio.h:31, from /usr/include/stdio.h:70, from ibex_block.c:9: /usr/include/_G_config.h:47: field `__cd' has incomplete type /usr/include/_G_config.h:50: field `__cd' has incomplete type /usr/include/_G_config.h:53: Internal error: Segmentation fault.
