<pre>test/asan/TestCases/Posix/wait4.cc has been failing on and off recently when
self-hosting trunk (Release+Asserts) on my PPC64/Linux POWER7 system running
REL 6.5.
error: expected string not found in input
// CHECK: {{in .*wait}}
The actual output looks something like this:
==15206==ERROR: AddressSanitizer: stack-buffer-overflow on address

The problem seems to be that we're not getting the function names printed;
perhaps this is a problem with the debug information?</pre>
