[Bug c++/38663] New: OpenMP directive causes internal compiler error

The code compiles without warning if I comment out the omp pragmas.

(Where/how do I upload the .ii file?)

Debug build works just fine.  -O2 and -O3 both fail.  Release build is fine
with g++4 on linux.

So what gcc are you using? 4.4 (which revision) or 4.3.0 20080125?
In any case, this compiles just fine for me with both 4.3.2-RH and 4.4 trunk.

OOH -- ICE ==  internal compiler error.

It's a bus error.

I downloaded gcc4.4 as a package here:

http://hpc.sourceforge.net/

taking the intel mac version:
gcc-intel-bin.tar.gz

With that installation came g++4.3.  Go figure.

If 4.3.0 is not the latest release of an intel-mac compatible g++, can you
point me to where I can download it?  (I'd greatly prefer not to build from
source, as my previous experiences doing so have been unpleasant).

Line 314 is the next non-whitespace line after the end of the omp parallel
block.

--- Comment #8 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This was mostly fixed in GCC 4.6.0 with the rewrite of the emulated TLS
support.

Darwin still uses emulated TLS even today.
