problems with the squid-2.5 connection pinning

I've found a problem with the connection pinning:

2006/04/13 11:50:25| fwdConnectStart: Pinned connection to mail.aiondiagnostics.com:80 gone, aborting request
2006/04/13 11:50:25| assertion failed: forward.c:114: "!EBIT_TEST(e->flags, ENTRY_FWD_HDR_WAIT)"

As far as I can tell:

* this fail occurs, storeAbort() is called
* .. which registers an event to clean up
* the event gets called:

#0 0xb7e4f83b in raise () from /lib/tls/libc.so.6
#1 0xb7e50fa2 in abort () from /lib/tls/libc.so.6
#2 0x08069e89 in xassert (msg=0x0, file=0x0, line=0) at debug.c:415
#3 0x08070743 in fwdStateFree (fwdState=0x2e026150) at forward.c:120
#4 0x0806dc3d in eventRun () at event.c:147
#5 0x0808eb45 in main (argc=0, argv=0x1) at main.c:769

And it goes bang.

Any ideas/suggestions?

This is squid-2.5-cvs with epoll, tproxy (not being used atm), wccp2 and pinned connection
support.
