I don't have a reduced testcase yet. the unreduced test case is that the upstart build in Ubuntu raring hangs in the testsuite with: Testing job_deserialise() ptrace handling BAD: wrong value for job->goal, expected 1 got 0 at tests/test_job.c:7331 (deserialise_ptrace_next). still trying to isolate the failure. afaics, it is not architecture specific. Even if backports are tested together, it would help if independent patches could be committed separately to the branches.

[Bug go/56432] New: libgo check should behave like the check target for all other target libraries
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56432
Bug #: 56432
Summary: libgo check should behave like the check target for
all other target libraries
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: go
AssignedTo: i...@airs.com
ReportedBy: d...@gcc.gnu.org
the libgo testsuite unfortunately works not the same as all other testsuites
for the target libraries do work. Usually if you do want to test a multilib
build, you call
RUNTESTFLAGS="--target_board=unix\{,-m32,-mx32\}" make -k check
and only the check target for the default multilib is called. The check target
doesn't descend into the multilib directories. libgo however descends into the
non-default multilib targets and calls check there too. And then with the above
RUNTESTFLAGS, every go test is called nine times instead of three times, and
apparently fails the other six times.
Otoh, running the test without RUNTESTFLAGS, and having at least a multilib
which can't be run on the current kernel, tries to run all multilib
configurations, and fails every test in these (this is a common use case on
build daemon machines running kernels of an older release).
Please let libgo behave the same as the other target libraries for the check
target, even it does introduce some delta.

You did change the code to use find_a_file which searches only for files with the x bit set. Work around is to install the plugin with the x bits set, or use some helper function which doesn't look for the x bits. I assume that wasn't catched, because the plugin then was found in another location? gcc.c has a static find_a_file function which does allows to specify the permission flags you want to search for.
