 Bug #: 56694

   Summary: Internal compiler error when compiling OpenMP code

Classification: Unclassified

   Product: gcc

   Version: 4.8.0

Status: UNCONFIRMED

  Severity: normal

While compiling my GammaLib suite with the new gcc 4.8.0 an internal compiler

error occurred in a routine that uses OpenMP for multi-threading. The following

message occurs:



GObservations_optimizer.cpp: In member function 'virtual void

GObservations::optimizer::eval(const GOptimizerPars&)':

GObservations_optimizer.cpp:431:1: internal compiler error: in change_scope, at

final.c:1575

Okay, here it comes. But believe me or not: with the -save-temps option the
code compiles through!

I rechecked by removing the option, and the code fails again. Putting it back
makes it work ... so this is a repeatable experiment.

Cheers,
