Bug #: 51522
Summary: ICE in gfortran 4.6.2, x86_64
Classification: Unclassified
Product: gcc
Version: 4.6.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: adr...@llnl.gov
Created attachment 26066
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26066
this one is only reproducible when the modules are spread over multiple files
I accidentally created this ICE while I was delta-debugging Bug 51520; my
script was only testing for *any* Segmentation fault instead of a specific one
;-)
The machine is running Ubuntu 10.04, 64 bit on an Intel Xeon.
