--- Comment #5 from Jack Howarth <howarth at nitro dot med.uc.edu> 2012-12-14 20:30:26 UTC ---
Appending -fsanitize=address to the compilation of the failing eh-1.exe
testcase on x86_64-apple-darwin10 produces the following output on execution of
eh-1.exe...

ASAN:SIGSEGV

whereas appending -fsanitize=address on x86_64 linux produces no output on
normal execution of the non-failing testcase with emutls.
