Hello shashikanthirem,

You've probably trashed the stack or heap. The error would suggest it's more likely to be the heap, but there's no guarantee stack corruption isn't the cause. The corruption is occurring prior to this function being called.

The SIGABRT signal can be caught, but it cannot be blocked; if the signal handler returns then all open streams are closed and flushed and the program terminates (dumping core if appropriate). This means that the abort call never returns. Because of this characteristic, it is often used to signal fatal conditions in support libraries, situations where the current operation cannot be completed but the main program can perform cleanup before exiting. It is used when an assertion fails.

 

Regards
