I don't see anything obviously wrong with your code, but you use lots of variables you don't show being defined, so it's very difficult to say. Post more of your code.
Since you're dealing with structures of pointers it's possible for a bug earlier to crash the code later -- a bad pointer gets stored, and the crash only happens when you use the bad value...

I have a simple code which does some computation by matching string patterns.
In brief:

crashdc(8) System Manager's Manual crashdc(8)
NAME
crashdc - Diagnostic data collection for a running or crashed system
SYNOPSIS
/usr/bin/crashdc [system-kernel] [core-image]
DESCRIPTION
The crashdc utility examines the core image of the operating system to extract critical diagnostic data. This utility is a shell script
that invokes several tools and commands that extract selected parameters of a running or a crashed system (for example, system configura-
tion, running processes, and panic messages).
The arguments to the crashdc utility are the system kernel and the core image. The default values are /vmunix and /dev/mem, respectively.
If you specify no arguments, the crashdc utility examines the running system.
The system usually invokes the crashdc utility during system startup. If the most recent core dump has been saved by the savecore command,
both the core image and the system kernel (respectively vmcore.n and vmunix.n, where the variable n is the crash number) are saved in the
crash directory (by default, /var/adm/crash). Also, the crashdc utility saves the output as the file crash-data.n (where the variable n is
the crash number) in the crash directory. The crashdc utility is invoked only if crash-data.n output in the crash directory does not exist
or is not from the most recent crash.
