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
