llvm dev - Jul 2014 - [LLVMdev] Sanitizer test failure

I'm compiling compiler-rt via CMake+Ninja on x86_64+ArchLinux and one
of the tests fails on ToT:

MemorySanitizer :: chained_origin_with_signals.cc

The text expects uninitialized warnings while the execution prints
nothing, thus FileCheck fails.

Anyone seeing this?

cheers,

Hi,

is it still an issue?
Just by looking at the code, I don't see why it could fail. Do you
need any help debugging it?

Hi Evgeniy,

Yes, it is. The problem here is that the program doesn't fail on my
box (release and debug builds), so I have no idea how to debug the
problem. According to the test, it's ran as "not
chained_origin_with_signals.cc.tmp", expecting it to fail. Also, the
FileCheck expects to find warnings on the output, for which there is
none

Maybe I'm missing some CMake flag or library, and that's why the
signal functionality is not working on my box?

cheers,
--renato
