Bug Report


From: Mike Baranski
Subject: Bug Report
Date: Wed, 09 May 2001 07:18:39 -0400

Dear Sirs,

This is a bug report.  Put a breakpoint at the comment in the source
below, and then try to plot the history of a using the plot menu item.
This caused ddd to core dump when I tried it.  If you need more system
info than is in the log file, just let me know.

MWB.
