Greetings! This has already been reported as bug #61342 for 2.7. See also Gentoo downstream bug report: https://bugs.gentoo.org/805578
I tried 2.8 and complex/test_c11 fails here too. gdb gives me the following backtrace: # gdb ./complex/test_c11 GNU gdb (Gentoo 15.2 vanilla) 15.2 Copyright (C) 2024 Free Software Foundation, Inc.
