Yesterday I tried building gcc again for the first time since two weeks and encountered what looks like an endless loop.
This command:
stage2/xgcc -Bstage2/ -B/opt/gcc/4.1-devel/x86_64-suse-linux-gnu/bin/ -c -g -O2
-gnatpg -gnata -g -O1 -fno-inline \
-I- -I. -Iada -I/cvs/gcc/gcc/ada /cvs/gcc/gcc/ada/a-except.adb -o ada/a-except.
o
was running for several hours.
Attaching gdb shows:
Attaching to program: /builds/gcc/misc/gcc/stage2/gnat1, process 32744

If I let it run for some time, it still shows:
(gdb) c
Continuing.
Program received signal SIGINT, Interrupt.

This is with current GCC mainline and happens on both Linux/x86-64
and Linux/PowerPC for me.
Anybody with the same problem?
I'll do a binary search now to figure out which patch broke this,
Andreas
