Can you run the failing command manually in the build directory under gdb to find where it traps? Created attachment 901671 [details]

I recompiled it using gcc-14 but it still failed. It never failed before. My gcc-14 and mold are built on gcc-15. I think you need to figure out which part of your system is miscompiled. I'm using GCC 15 (and mold + lto) on various systems and had no issues. Please also keep in mind that given the flags you mentioned in another bug, it's not always enough to just rebuild _one_ thing with safe flags. It might be that a dependency is contaminated. It seems that gcc 15 has broken too many things. I don't want to move further because I have reinstalled my system. I really think it's more about the flags, but it is what it is now. |
