Question

We are currently doing platform migration from sun solaris  to HP-UX   B.11.31.

version:
HP-UX hva03ads B.11.31 U ia64 0291095592 unlimited-user license

compiler: 

Hewlett-Packard Company           - 41 -          HP C/aC++ Version A.06.25

On sun solaris unix it worked fine.  When I am executing on HP it showing coredump error.

When i am trying to debug corefiles with gdb  <binary filename>  <corefilename>

It shows the following warnings:

HP gdb 6.1 for HP Itanium (32 or 64 bit) and target HP-UX 11iv2 and 11iv3.

Answer

This issue is raised due to  insuficiant allocation memory for a string.

ps_sc_nom_fic = (char *)malloc((strlen(ps_local)+strlen(ps_cs_ipn)+strlen(ps_type)+strlen(ps_num_jd)+strlen(ps_complement)+1)*sizeof(char));

After adding sufficient size, now it is working fine.
