[Bug middle-end/41429] New: gomp tests timeout with -fpic

[ghazi at gcc dot gnu dot org]

Somewhere between mainline revision 151676 and 151704 I started getting several
gomp failures which manifest as timeouts in the testsuite when using
-fpic/-fPIC.

Here are the differing testsuite results:
Clean: http://gcc.gnu.org/ml/gcc-testresults/2009-09/msg01244.html
FAIL: http://gcc.gnu.org/ml/gcc-testresults/2009-09/msg01344.html

The new gomp failures with -fpic/-fPIC are:

------- Comment #1 from ghazi at gcc dot gnu dot org  2009-09-21 15:04 -------
To reproduce, target x86_64-unknown-linux-gnu and compile g++.dg/gomp/pr37189.C
with:

cc1plus -quiet -v pr37189.C -dumpbase pr37189.C -mtune=generic -auxbase pr37189
-version -fopenmp -fpic -o pr37189.s
------------------------------------------------
// PR c++/37189
// { dg-do compile }
// { dg-options "-fopenmp" }

struct S
{
  S () {}
  S (S const &) {}
};

struct T
{
  S s;
};

void
bar (T &)
{
}

int
foo ()
{
  T t;
  #pragma omp task
    bar (t);
}
