Summary: ICE: gfortran dies when '-finstrument-functions'
option is used
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: mg1...@web.de
Created attachment 24063
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=24063
Preprocesses input file, generated by '-save-temps'
When compiling the attached source file with gfortran 4.6.0 and the
'-finstrument-functions' option specified, gfortran dies with a SIGSEGV.
Without the option and with previous versions of the compiler (e.g., 4.5.2),
compilation works fine.
