Caught signal 11: SIGSEGV

i guess that's because it must use old style _GSINIT section for that, not new _INITIALIZER/_INITIALIZED

Fixed in [r13842].

The underlying issue was a check for the possibility of tail-call optimization in code generation, which assumed that is was generating code for a function (as opposed to the intialization of a file-scope object). Similar issues existed for stm8 and mcs51.
