g77 2.96 (on redhat-7.3) -- symptom also appears in the g77 of
redhat-6.2 but I don't have the version to hand -- and Intel Fortran
The debug info was the default from the -g option. I've now also just
run g77 with -gdwarf and the same problem arises..

Beats me ;-) -- a good googling uncovers g77 probably has its problems
-- but as gdb doesn't get it right all the time for either compiler,
whichever format is correct we need to do something in gdb to be
I think using the gcc_compiled flag is the way to go to merge the
patches into one gdb build. I know it seems like a hack, but it seems
a whole lot easier than getting folks to change either the Intel or
GNU compiler. It looks like the issue has been known about for a long
time so perhaps the compiler people just can't agree?

No probs -- will contact the appropriate folks at FSF (unless you have
one to hand)
