insight crash

[Barry Branham <bbranham at networkusa dot net>]

Hi,

Insight crashes when I run it on on RedHat 7.0.  I was using it
previously on RH 6.2 and it ran fine.  I recently upgraded to RH7.0 and
installed insight+dejagnu-20001213.  It config'd ok, make'd with minor
warnings and installed ok.

When I run with an executable as argument, it a long time passes and
then it seg faults.
Without an argument it displays an empty source window - no menu bar etc
but doesn't crash.

Today I got similiar results with insight+dejagnu-20010106.
When it crashes, 'gdb /usr/local/bin/gdb core' (regular gdb) gives the
following:

subsequent frames repeat...

So it looks like we're running out of memory.  Running top during this
shows size getting up to 25Mb before the segfault.

Any help much appreciated.
