Segmentation Fault on 64-bit gcc Compiled Pro*C Program on HPUX 1 1.00

Segmentation Fault on 64-bit gcc Compiled Pro*C Program on HPUX 1 1.00

[Choiniere, Jacques C, PERSCOM]

NOTE:  THIS IS A RETRANSMISSION:
To Whom it may concern,

I am getting the following Segmentation Fault during runtime.  The fault is
occurring in an fgets statement that contains no Pro*C constructs.

MY GENERAL ENVIRONMENT:
"I am in the process of upgrading from an Oracle 7.3.4 environment using
Pro*C and an HP 32-bit C Compiler  (version A.10.32) to an Oracle 8.1.7
64-bit environment using 64-bit Pro*C and a GNU (gcc) 64-bit C Compiler. All
software is on an HP UNIX version 11.00 box.

Specifically, during runtime I am experiencing a SEGMENTATION Fault on the
/usr/lib/libc.2 library when the program executes a fgets() C-statement. " 


MY COMPILE STATEMENTS:
