Hi All
I get a SIGSEGV exception in OpenSSL from lNet on application exit
when I use lNet together with PQConnection.

I can't really continue working without using these two components. I
will appreciate any ideas, fixes or workarounds.

I can use both components independantly, but not in the same app.

The procedure to replicate is:

New project
Drop lNet TCP componet
Drop PQConnection

With PQConnection fill in in Obj Inspector
DatabaseName := testdb
Hostname := 127.0.0.1
Password := test
UserName := aname
Connected := true <---IMPORTANT

Run
Exit

Get exception 'External: SIGSERV' at
ErrRemoveState(pid: cInt) {OpenSSL.pas 1001:15}

My current setup is:
Kubuntu 8.10 i386
Lazarus 0.9.26 beta (2009-2-20)
FPC 2.2.2
lNet 0.6.2 (0.6.3 also have the problem)
libssl 0.9.8
libcrypto 0.9.8

Thanks
Wimpie

If anybody is interested, this exception can be prevented by
commenting out the lines in the initialization and finalization
sections of lNetSSL.pp.

This will most likely break SSL functionality, but solves the problem
for the moment.
