This is just a heads up: Most recent glibc development snapshot, more specifically commit 2ecccaede9097f867284d352a881d8f226ba4fb7 ("stdlib/setenv.c (__add_to_environ): Dump core quickly if setenv (..., NULL, ...) is called.") breaks gcc-config, and so far the emerge and gdb wrappers as well, in that they segfault almost immediately. https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=2ecccaede9097f867284d352a881d8f226ba4fb7 I'm marking this as minor since mainline gentoo isn't going to be affected by this for a long time. Reproducible: Always
The glibc developers changed their mind.
