Re: GCC 2.95.2 & Purify

Hi,

        I've been using gcc 2.7.2.1 on my Solaris
        2.5.1 operating system for some time
        now with "purify" and I have had no problems.

        I downloaded and built gcc 2.95.2 on my
        Solaris 2.5.1 system.  Now, when I try
        to compile my code with it and link
        it with "purify" I get warning messages
        (see below). Then when I try to run it,
        I get a core dump.  I tried to debug it
        with "gdb" but I get generally strange
        behavior  (like stepping through the code
        of a CASE statement incorrectly and
        incorrectly evaluating IF statements etc.).

        When I link I get the following:

    purify gcc sens_main.o sens_info.o sens_go.o taskPrimary.o taskModel.o
    gen_sensdata.o op_version.o GradTask.o
