--- Comment #12 from Iain Sandoe <iains at gcc dot gnu.org> 2011-10-11 18:45:39 UTC --- Created attachment 25466 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25466 test of -fstack-check a simple test program for Darwin .. .. AFAICT this DTRT under 'c' on {powerpc,i386}-darwin9 and also on x86_64-darwin10. If one bumps up the stack usage in stack_meltdown() then checks the tree dumps, __builtin_alloca is being invoked - but still things seem to be as expected.
