This mostly happens when gcc is invoked through nvcc, i.e. https://github.com/NVIDIA/nccl/issues/494 It looks like a regression in recently stabilized 10.3.0 over 10.2.0. Typical errors look like: /usr/lib/gcc/x86_64-pc-linux-gnu/10.3.0/include/g++-v10/chrono:428:27: internal compiler error: Segmentation fault 428 | _S_gcd(intmax_t __m, intmax_t __n) noexcept | ^~~~~~ 0xc531cf crash_signal /var/tmp/portage/sys-devel/gcc-10.3.0/work/gcc-10.3.0/gcc/toplev.c:328 0x7f973932478f ??? /var/tmp/portage/sys-libs/glibc-2.33/work/glibc-2.33/signal/../sysdeps/unix/sysv/linux/x86_64/sigaction.c:0 0x72bba3 tsubst(tree_node*, tree_node*, int, tree_node*) /var/tmp/portage/sys-devel/gcc-10.3.0/work/gcc-10.3.0/gcc/cp/pt.c:15310 The upstream issue at $URL contains a fix that reportedly works.

@slyfox, once Patrick Palka has backported these fixes, could we cherry-pick them?

Should be fixed in gcc-11.1.0-r1 and gcc-10.3.0-r1.
Thanks! Somewhat late, but I can confirm dropping the patch to /etc/portage/patches fixed the problem for me.
