Hi Paul,
Yes, it looks like there is an open bug against gdb
6593753 gdb cannot read corefiles from gcore on Solaris 10
which behaves the same in the current development release (Nevada).
The current plan is not to upgrade software, although
gdb could be upgraded in a separate case. This wouldn't fix things...
The current gdb in Solaris is version 6.3, but I also
tried reading a gcore-generated core with the latest gdb
(version 6.7.1), and the above reported problem still occurs.
However, gdb is not completely broken--as far as I can tell, gdb can
debug gcc- and Sun Studio 11-compiled binaries, including
core files generated (not via gcore) when executing those files.
Thanks,
April
