ktkachov at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ktkachov at gcc dot gnu.org --- Comment #1 from ktkachov at gcc dot gnu.org --- GCC 4.9 is no longer supported. Please try a newer version (GCC 5 and onwards). In any case, this looks to me like the kernel killing the process because it used too much memory. Try adding some swap memory.
