If you try compiling using gcc -v compilerbreaker.c, you will see the exact
commandlines that the gcc driver is using to execute cc1obj. Presumably if
you run cc1obj yourself using the identical args, you'll get a nice core
dump...

I say presumably, because trying to use -fgnu-runtime with an Objective-C
program as you described does not crash for me.
