Description Stepan Broz 2025-01-24 16:24:29 UTC

While compiling a source file from the dhcp project the compiler crashes with ICE:

Does not reproduce in mockbuild on f40.

Comment 1 Dave Malcolm 2025-01-24 16:34:08 UTC

The error message matches this upstream bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=118429 though I don't know if it's the same issue as seen there.

Comment 2 Stepan Broz 2025-01-24 17:00:08 UTC

Issue is aarch64 specific, all other arches build fine:
