Oh! Given your previous comment about there not being any user-defined
aggregates, I see what the problem is. AIX must be one of the platforms
where malloc(0) is defined to return NULL rather than a pointer to a
zero-size block. pg_malloc is not coping with that.
A quick fix would be
pg_malloc(size_t size)
{
void *tmp;
tmp = malloc(size);
- if (!tmp)
+ if (!tmp && size)
{
psql_error("out of memory\n");
exit(EXIT_FAILURE);
}
but I'm not sure if that's the best answer overall. Will take it up in
-hackers.
