What it looks like to me is something clobbering memory, eg writing more data into a palloc'd memory chunk than will fit; which results in overwriting malloc's own data structures, causing malloc to complain when it notices. Whether it's your bug or something wrong in the beta is hard to say. > pd: gdb can help? ( for debugging my own code) --enable-cassert would probably help more, since it would turn on some clobber-detection support in PG. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to majordomo@xxxxxxxxxxxxxx so that your message can get through to the mailing list cleanly
