llvm dev - Feb 2015 - [LLVMdev] [lld] Need help: "buildbot failure in LLVM on lld-x86_64-freebsd"

Hey,

I was just informed that my ScalarEvolution patch failed the lld tests
on x86_64-freebsd, however on my machine x86_64-linux all tests
(llvm+lld) pass for a debug as well as a release build. Furthermore, I'm
a bit confused about the error message just before the segfault happens:
  "Unable to find lib.exe in PATH"

Could somebody help me track down the problem?

Thanks in advance,
  Johannes

I tried to reproduce this locally (on FreeBSD stable/10) but the test
does not fail here. I'm not sure what happened, but agree it's hard to
see how your change would cause such a failure.

I started another buildbot run at the same revision and it passed:
http://lab.llvm.org:8011/builders/lld-x86_64-freebsd/builds/10260

Thanks for looking into the problem!

Since a second run passed, I will probably just wait and hope there
won't be any complaints in the future.
