Re: Patches for GNU/Linux PPC native now in CVS

[Kevin Hendricks <khendricks at ivey dot uwo dot ca>]

Hi Kevin B.

Here is my first bug report.  This is with gdb from today's cvs (after your
later commit) debugging a problem with Motif Drag-n-Drop in the jdk under
native threads.

Everything was working fine until I decided to rerun the program from within
gdb without removing my shared library breakpoints first.

Here is the resulting log file.  Notice the non-existent breakpoint 0 and also
even through I manually removed all of my breakpoints and tried to continue I
could not do so.

I hope this info helps.  The only simple test case would be to actually run the
DDTest java program under the jdk with Motif source around.

Let me know if you would like more info about this bug (explicit steps to try)
and I would be happy to follow instructions.

Thanks,

Kevin H.
