[Bug libgomp/26611] New: openmp gomp ICE at gimplify.c:4257

[Bug libgomp/26611] New: openmp gomp ICE at gimplify.c:4257

[bowie dot owens at csiro dot au]

I consistently get the following ICE on this C++ code.

omp_harness.cpp:39: internal compiler error: in omp_add_variable, at
gimplify.c:4257

The code is not legit and there are several errors but this is because I have
cut down a larger program.

I am using the gomp-branch and gcc -v reports:

Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../gomp-20050608-branch/configure
--prefix=/local_scratch/owe043/gcc_gomp
Thread model: posix
gcc version 4.2.0-gomp-20050608-branch 20060216 (experimental) (merged
20060216)

The command line I used to compile was:

g++ -save-temps -fopenmp omp_harness.cpp

preprocessed output from save-temps that triggers ICE

GZIP compressed to make it within the size limit. Will try and make a smaller
example that doesn't involve valarray or iostreams.

simpler preprocessed C++ code that causes ICE

Removed include of valarray and iostream to produce simpler preprocessed C++
code that still triggers ICE.

Confirmed, reduced testcase:
int t;

void search()
{
#pragma omp parallel for
 for (int i = 0; i < 1000; ++i) try {
   mm::print(t);
 }catch(...){}
}

This is actually ICE on valid, a small modification of the testcase
that makes it valid still ICEs.
