From Bugzilla Helper: User-Agent: Mozilla/4.75 [en] (X11; U; Linux 2.4.2-ipsec-low i686) I have an Objective-C file that causes gcc-objc-2.96-69 to die with a segmentation fault each time I try to compile it. Reproducible: Always Steps to Reproduce: 1. gcc -g -O -Wall -D_REENTRANT -D_GNU_SOURCE -I../include -I/usr/include/pgsql -I../protocol_lib -I../tbot2 -c -o Game.o Game.m Actual Results: Game.m:1861: Internal error: Segmentation fault. Please submit a full bug report. Expected Results: Program should have compiled into a .o file. I can e-mail a pre-processed .m file that exhibits this crash to whoever wants to reproduce this bug.
There was a GC related bug in Objective-C frontend, which was fixed in gcc-objc-2.96-76. Could you try that compiler (or newer, such as the one released in the 7.1 distribution)? If not or if you can reproduce it even with that compiler, please use the attach button on this page to attach preprocessed Game.mi. If that compiler fixes it, please let us know as well.
