[Bug libgomp/28046] New: libgomp test pr27337.C fails intermittently

["janis at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

My mainline testing gets intermittent failures for test
libgomp/testsuite/libgomp.g++/pr27337.c.  Some of the failures are due to wrong
counts from the constructor and destructor after the call to foo, and others
are for wrong values of x.i (with values in the range 19-27) after the call to
bar.  The percentage of failures depends on which system I test on, but I
haven't figured out the significant factors: CPU type, number of processors,
binutils version, kernel version, load on the system

I haven't studied omp programs; the failures could be due to errors in the test
itself.  The failures occur at all levels of optimization.

I get this failure on powerpc*-linux (with both -m32 and -m64) and on
x86_64-linux.
