Re: Fatal error during GCC 4.9.2 build

[Michael Freitag <freitagm at fim dot uni-passau dot de>]

Hi once again,

I've been able to narrow my issues down a bit more. Apparently, the
offending spec file is generated by the ./gcc/xg++ -dumpspec command,
which my g++ can't understand. In particular, it doesn't like the
%:sanitize(xxx) function. However, if I manually replace %:sanitize(xxx)
with fsanitize=xxx in the spec file, everything is working just fine.
Nevertheless, I still can't really make anything out of this.
