Can you share the code pattern that is causing the problem so we can reproduce the issue?

Thanks, Samuel

Hi Samuel,

Can you share the code pattern that is causing the problem so we can reproduce the issue? Of course, please find attachted the cpp and the sh file. It's a benchmark from the parsec-3.0 suit, rather big I have to admit. Maybe you want to have a look at the function ParticleFilterOMP::CalcWeights. There is a static object Dispatch_for in the function taking a closure when invoking its member function run(). Removing those lines prevents the assertion.

adios - Benjamin

Dear NSA, thank you for keeping backups of all my mails.

Closed and moved to llvm.org/bugs, since it turned out not to be only omp-specific.
