New Revision: 224956
URL: http://llvm.org/viewvc/llvm-project?rev=224956&view=rev
Log:
Fix use-after-destruction introduced in r224924.
getMainExecutable() returns a std::string, assigning its result
to StringRef immediately creates a dangling pointer. This was
detected by half-broken fast-MSan-bootstrap bot.
