Extended Description

BugPoint tests fail, printing "Program could not be executed". An strace shows that the failure originates when the dynamic linker tries to load libLLVMARMInfo.so, and it dies with a memory related error: "failed to map segment from shared object: Cannot allocate memory."

This appears to be caused by the deafult rlimits set in "lib/Support/Unix/Program.inc". Passing '-mlimit=0' into the tests allows them to pass (see attached).

Please send patches to llvm-commits.

I can confirm this, had the same problem (linker failed to load libLLVMX86Info.so), applying the patch solved the problem. No idea why this error happenes only on one of our machines though.
