Bug #: 50178
Summary: [4.6 regression] ICE with gfortran -O3, not with
gfortran -02
Classification: Unclassified
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: toon@moene.org
Created attachment 25089

Source code of the failing compilation.
Compiling the attached source code with gfortran 4.6.1 using optimization -O3
leads to the following Internal Compiler Error:
$ gfortran -O3 -c suedyn.f90
suedyn.f90: In function âsuedynâ:
suedyn.f90:10:0: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
Compiling with -O2 instead succeeds (hence my suspicion that it is a middle-end
failure).
