Purify-4.5.1-Solaris 2.x with egcs-2.91.66

[Priya Narasimhan <priya at lambda dot ece dot ucsb dot edu>]

Hi,

I am trying to evaluate Rational's Purify-4.5.1 on a Solaris 2.5.1
machine. When I compiled my program using g++ from the
egcs-2.91.66 distribution, using libstdc++.so.2.9.0, 
my program quits with a SIGSEGV and a core dump as soon
as the Purify viewer is launched. This is the output
from Purify

When I compile the same program with the Sun SparcWorks 4.1 compiler,
Purify seems to work, and does not cause the program to die.

Is this a well-known problem, or am I missing something here?

Thank you in advance for your help and suggestions.
