PostgreSQL: Crash on Disconnect

I am getting a consistent crash on disconnecting from my PostgreSQL server (v9.2.4). It appears to be crashing on some sort of access violation within the SSLEAY32.dll file. I am using the latest build of HeidiSQL (Portable). Below is the text of the crash log:

Any ideas what might be causing this, or are you aware of any potential work-arounds? thanks.

Yes, PostgreSQL connection crashes in libpq.dll->PQfinish when using the 32bit executable. I have no clue why yet. See here:

Note: That crash does not happen in the 64bit version of HeidiSQL, which uses the 64bit libpq.dll.
