This has been discuss long ago,
and I thought it was in CVS already for a long time,
but apparently noone committed it.
Back in september 200, I probably didn't dare to commit it myself,
but my commit list grew quite a lot since that time!
See http://sources.redhat.com/ml/gdb-patches/2000-09/msg00107.html
If I get an second approval from
any of the Blanket Write Privs (as blockframe.c
does not seem to belong to some designated group),
I will commit this ASAP.
ChangeLog entry:
2000-09-12 Pierre Muller <muller@ics.u-strasbg.fr>
* blockframe.c (get_pc_function_start): return 0 if the minimal symbol
found is not inside a section.
