installed libsigsegv and was able to re-emerge gcc
Regarding request for additional info: libsigsegv was not installed on my system. May be it was earlier, but --depclean deleted it. I've looked into gcc's ebuilds and the lib is not listed as dependency.
It looks like m4 was linked against libsigsegv: m4: error while loading shared libraries: libsigsegv.so.0: cannot open shared object file: No such file or directory bison: subsidiary program `m4' not found However, it did not have an explicit dependency on libsigsegv, but rather found it happened to be installed and used it. Thus m4 got broken when you did a depclean and whatever package explicitly asked for libsigsegv was gone.
Fixed in 1.4.14-r1.
