[llvm-commits] [PATCH] Handle realpath NULL pointer return value

[Kovarththanan Rajaratnam]

Hey,

Is it OK if I commit the following:

This patch ensures that Path::GetMainExecutable is able to handle the
case where realpath() fails. When this occurs we segfault trying to
create a std::string from a NULL pointer.

Fixes PR5635.
