g++-mike-eh8-C test failure

["John David Anglin" <dave at hiauly1 dot hia dot nrc dot ca>]

I have examined the failure of g++-mike-eh8-C under hpux 10.20.  Gcc
was built with --enable-shared and CFLAGS="-g -O3".

The test dies with a segmentation fault in __eh_rtime_match:

int
__eh_rtime_match (void *rtime)
{
  void *info;
  __eh_matcher matcher;
  void *ret;

  info = *(__get_eh_info ());
  matcher = ((__eh_info *)info)->match_function;
  if (! matcher)
    {
#ifndef inhibit_libc
      fprintf (stderr, "Internal Compiler Bug: No runtime type matcher.");
#endif
      return 0;
    }
  ret = (*matcher) (info, rtime, (void *)0);
  return (ret != NULL);
}

The segmentation fault occurs because the pointer info returned by
__get_eh_info is NULL.  Should there be a test similar to the one
for matcher?  Since the test does not fail when linked with "-static",
it looks like the failure occurs because the _eh_info structure is
not being properly setup with the shared version of libstdc++.
