When issuing emerge sys-devel/gdb, the compile stops with :-

Hi! This would be a bug in GCC.

Can you look at https://wiki.gentoo.org/wiki/Gcc-ICE-reporting-guide?
Comment 2 MarcT 2021-09-22 22:41:12 UTC
I updated my CFLAGS to ="-mieee -mcpu=ev67" (removing -O2) and re-ran the emerge.

it used to fail like this

make[3]: Entering directory '/var/tmp/portage/sys-devel/gdb-11.1/work/gdb-11.1/g

Now it passes by and completes the emerge.

I'll add the -O2 again and see if it errors.

additionally, note the ICE does not generate a segfault. Ive no memory issues, not using -pipe etc.

This appears to have been a memory/hardware issue possibly relating to an ELSA Gloria graphics card. I noticed when undertaking a compilation free memory would dip into the 20MB range (while the bufcache was 600MB). I set min free memory through the kernel tunable but this had no positive effect. Every compile caused low memory like this, _but only when undertaking the compilation on the console itself_. When I compiled via ssh, free memory never dipped below ~500MB (total 1GB). So something about the ELSA, maybe the fb device, maybe it was faulty, was consuming memory as the build progressed until the enevetable ICE. I swapped to a Trio64 and its compiling from the console now. Weird thing, no compilation crashed, ever, from the livecd with the ELSA present. I'm going to get another ELSA and try that. Thanks.
