Hi all,
In exactly 3 places of the ECPG driver (for numeric, for interval and
for date), we do something as follows:
/* Allocation of mallocedval */
if (!(mallocedval = ecpg_strdup("array [", lineno)))
return false;
for (element = 0; element < var->arrsize; element++)
{
int result;
ptr = stuff_alloc();
if (!ptr)
return false; <= Leak here of mallocedval
It happens that if the allocation done within this for loop fails we
leak mallocedval that was previously allocated. Attached is a patch to
fix this issue spotted by Coverity.
I think there are more similar leaks nearby. After the first hunk,
there's another if-check with "return false" that also leaks
mallocedval. Right after the two other hunks, if the ecpg_realloc fails,
we again leak mallocedval.
I wonder why Coverity didn't warn about those? Maybe it would've, after
fixing the first ones.
