Sarah Morgensen skribis: > Configuring with "--disable-stackvma" seems to fix this. Doing this > makes libsigsegv use a different heuristic for determining if a SIGSEGV > was a stack overflow. I don't think it should impact functionality. > Perhaps just apply that to aarch64 until there's a proper fix? Sounds like a good interim measure, for aarch64 and powerpc at least as Efraim writes. If you can come up with a patch, we could apply it in the upcoming rebuild. Thanks, Ludo=E2=80=99.
