5800c7271c Check return code of pthread_create and bail out if 
the function failed. This helps on systems which don't
have lots of memory.

74c0b9293d Due to a kernel bug the siginfo struct was not filled in correctly. 
The si_code was incorrect not matching any of the VKI_ILL_....
cases checked in m_signals.c function default_action.
So let's have two expected output files for buggy kernels and otherwise.
Also, add op00 to the list of files to be ignored.

a71f5978fc Fix a Massif bug: when realloc'ing a block, any values in the part of the 
block beyond the original request weren't copied.  They are now.  This is
important because a program could use malloc_usable_size to gain legitimate
access to those extra bytes.

which is a minimum version number. Use os_test in the
prerequisite expression.

ab40e94dad drd: Fix a race condition in the barrier implementation that could result in false positives. 
What could occur before this fix is:
- The pthread_barrier() call in a first thread finishes.
- Another thread invokes pthread_join() on that thread, causing the information
  associated with that thread to be removed from the barrier object.
- The pthread_barrier() call in another thread finishes. Because some
  thread information has already been removed from the barrier object, the
  per-thread vector clock "last" won't be computed correctly by
  DRD_(barrier_post_wait)().
- Because of the above false positives could be reported.

This resulted in sporadic failure of the drd/tests/matinv regression test, and
should now be fixed.
