[plt-scheme] Caught the bug

Hi all,

Running DrScheme 301.6 on top of gdb finally caught the bug I've been
having and crashing drscheme all the time. To me the backtrace doesn't
tell me much. I'll leave my gdb open in case someone wants more
information. Here's the backtrace:
(gdb) run -synchronous -mvqM drscheme
Starting program: /usr/local/plt/plt-svn-180206/bin/mred -synchronous
-mvqM drscheme

Previous frame inner to this frame (corrupt stack?)

How can I provide more info?

Should I report the bug?

Cheers,
