My own benchmarks work fine (gcc/g++ also).  In John Campbell's test,
among 5 run-time failures, there is (twice):

Program received signal SIGSEGV: Segmentation fault - invalid memory
reference.

Backtrace for this error:
      1 [main] profile_omp 5664 fixup_mmaps_after_fork:
ReadProcessMemory failed
 for MAP_PRIVATE address 0x6FE5FC60000, Win32 error 998

      3 [main] profile_omp 4644 fork: child -1 - forked process 5664

  28628 [main] profile_omp 4644 cygwin_exception::open_stackdumpfile:
Dumping stack trace to profile_omp.exe.stackdump

In spite of the remaining failures, it looks like progress.
As I'm lazy, I'll continue using gcc-5.0 trunk builds unless there is
interest (suggestion what should be done) in this one.  I guess this
4.9.2-1 is more aggressive with build options than I've been able to
make work.
