--- Comment #11 from David Malcolm <dmalcolm at gcc dot gnu.org> --- Re comment #10: I just tested unknown-fns-4.c and malloc-vs-local-1b.c 500 times each on a --target=i386-pc-solaris2.11 build using the script from comment #8 and the results were identical each time. So hopefully the nondeterminism is fixed, at least.
