Created attachment 860451 [details] emerge info When I run distcc with "cc" or "gcc" as compiler, I get a segfault. This does not occur when using "aarch64-gentoo-linux-musl-gcc". System configuration: gentoo musl hardened profile. This problem does not occur on my laptop with non-hardened profile. I recompiled with address sanitizer and found the issue comes from the `dcc_gcc_rewrite_fqn` function. There is an upstream patch available. Unfortunately, the patch is from July 2021 and no release have been made since May 2021. This bug prevents from using distcc when the compiler is "cc", "gcc", "c++, ...

Maybe I should have selected the "Hardened" component rather than "Current packages" since it seems to only affect hardened profiles, but I'm not sure.
