I'm seeing a number of failures in different tests in the tree-prof
directory when I run make check in parallel none of which are
reproducible with -j1. I don't see anything about in Bugzilla or
in recent test results. Has anyone noticed this or am I missing
something?
This is on a 56-core x86_64 machine running Fedora 21 and DejaGnu
1:1.5.1-4.fc21 installed.
Thanks
Martin
Serial make check passes:
$ make -C /build/gcc-49905 check-c RUNTESTFLAGS='tree-prof.exp'
...
=== gcc Summary ===

Parallel make check fails a bunch of different tests each time
it's run:
$ make -C /build/gcc-49905 -j80 -k check-c RUNTESTFLAGS='tree-prof.exp'
