On master, with checking=all, I get dozens of fails for g++, already for months on end.

Compare a standard gcc build:

with this one using checking=all:

https://gcc.gnu.org/pipermail/gcc-testresults/2025-February/837708.html

Other languages do not seem to be affected.

A sample:

FAIL: g++.dg/modules/xtreme-header-8.C -std=c++17 (internal compiler 
error: Segmentation fault)
FAIL: g++.dg/modules/xtreme-header-8.C -std=c++17 (test for excess errors)
FAIL: g++.dg/modules/xtreme-header-8.C module-cmi xstd (gcm.cache/xstd.gcm)
FAIL: g++.dg/modules/xtreme-header-8.C -std=c++2a (internal compiler 
error: Segmentation fault)
FAIL: g++.dg/modules/xtreme-header-8.C -std=c++2a (test for excess errors)
FAIL: g++.dg/modules/xtreme-header-8.C module-cmi xstd (gcm.cache/xstd.gcm)

Hope this is useful.

Kind regards,
