Description:        Memory leak in informix.c
Details:

In file src/interfaces/ecpg/compatlib/informix.c:763

It seems to me that variable "temp" leaks memory here if initValue() fails:

        temp = (char *) malloc(fmt_len + 1);

        /* put all info about the long in a struct */
        if (!temp || initValue(lng_val) == -1)
        {
                errno = ENOMEM;
                return -1;
        }
