Re: gcc 3.1 and gdb 5.2?

[Doug Warmke <doug at ikos dot com>]

Hey, it worked!

Using the -gstabs option fixes the gdb 5.2 core dump.
And doing something like
    setenv SHELL /bin/sh
gets rid of the LD_LIBRARY_PATH mis-settings for csh users.

Is there any way to configure gdb *not* to load your
.cshrc upon invocation?  That is nasty behavior.
Moreover, if you get into gdb and LD_LIBRARY_PATH
(or any other env variable) is obviously set wrong,
and you do "show env LD_LIBRARY_PATH" inside gdb,
it will show you the environment of your original shell,
*not* gdb's actual environment.  Even nastier.

Thanks Joe.

Regards,
Doug
