[Q] Esql/c Core Dumps

hi! My platform is esql/c 5.0 on sunos 4.1.3. I am using the descriptor facility available to insert the records. Basically I set the data values of the descriptor with the values read from a file. If any field is not available i set the value to zero (note: It will be a charcter string and Informix will convert it to the required type i.e. integer) When a field is not available that is when i initialize it to ZERO, Informix is core dumping in the library function 'rstrdec'. This function gets called by the library function '_iqsetdesc' which sets the descriptor values. I guess this to be a library problem. Any help would be much appriciated.
