>Description:
Hi,

I've been trying to track a segfault in sqlite3 (3.7.11, ports package) when I use OpenDNSSEC 1.3.7 and SoftHSM 1.3.2.

I don't know if the issue is related to sqlite3 or to something in FreeBSD libc but it can be replicated by installing SoftHSM and OpenDNSSEC and then running "make check" in OpenDNSSEC (see https://wiki.opendnssec.org/display/OpenDNSSEC/Platforms#Platforms-FreeBSD9 for my setup).

NOTE: This only happens on amd64 and not 32bit system and I think it has something to do with tracking the size of the malloc's that sqlite3 memstatus needs.

Turning off MEMSTATUS for the sqlite3 ports package removes the problem.

I've reported this to the sqlite-users mailing list also.

Cheers,
Jerry

>Fix:
Deselecting MEMSTATUS in the config for sqlite3 ports package and reinstalling.
