Hi,
The following small program gives ICE when compiled like this:
g++ -Wall -fopenmp -O2 -I$POLDEST/ext/include -E -o./test_pp.cc ./test.cc
g++ -Wall -fopenmp -O2 -L$POLDEST/ext/lib -o./test ./test_pp.cc -lblitz -lgomp
./test.cc: In function int main():
./test.cc:3: internal compiler error: Segmentation fault
When removing the 'try-catch'-part it works fine.
----
#include <blitz/array.h>
int main()
{
try
{
blitz::Array<float,1> transOrig( 10);
blitz::Array<float,1> trans( 10);
blitz::Range myRange( 0, 9);
#pragma omp parallel for
for( int i = 0; i < 2; ++i)
{
trans += transOrig( myRange);
}
}
catch( std::exception)
{}
}
Here the preprocessed source: http://data.marssoft.de/attachment-bug-gcc.bz2
And my specs: ~> gcc -v
Using built-in specs.
