Re: Returning non-terminated string in ECPG Informix-compatible function

Greetings again.
I was looking through more static analyzer output and found another 
problem.
In ecpg/pgtypeslib/dt_common.c there are 4 calls of pgtypes_alloc.
This function uses calloc and returns NULL if OOM, but we don't check 
its
return value and immediately pass it to strcpy, which could lead to 
segfault.

I suggest adding a check for a return value since all other calls of
pgtypes_alloc are checked for NULL.

A proposed patch (with previous and current changes) is attached
