Wrong source code information in idb

Wrong source code information in idb


I have trouble with the ifort v9.1.036 Fortran compiler and the idb
debugger. The source files are preprocessed by the GNU C preprocessor
that inserts line number directives. When compiling the source with the
-g switch and examining a backtrace in idb all line number information
is wrong. I also tried preprocessing with the Intel fpp but that did
not help either. Is there some pitfall with that combination? Any help
is very much appreciated as debugging with wrong source code locations
is almost useless.

Best regards,

For more complete information about compiler optimizations, see our Optimization Notice.

I'd suggest that you report the problem to Intel Premier Support and attach a test case.
