FreeBSD euclid.vbnm.net 7.1-STABLE FreeBSD 7.1-STABLE #3: Mon Jan  5 13:30:54 EST 2009     dedrick at euclid.vbnm.net:/usr/obj/usr/src/sys/EUCLID-1  i386

The WindowMaker application wmbluecpu (in ports) now appears to be a runaway process after a recent upgrade.

I performed ports upgrades as specified in /usr/ports/UPDATING 20090123 x11/libxcb,  20090123,24 x11-servers/xorg-server.

wmbluecpu then seemed to be not working correctly.

I recompiled wmblue with debugging symbols and it seems to be spinning forever in callstacks like

#0  0x28267280 in _pthread_testcancel () from /lib/libc.so.7
#1  0x2829546c in _xcb_conn_wait () from /usr/local/lib/libxcb.so.2

#15 0x0804a6a5 in main (carg=256, varg=0x0) at wmbluecpu.c:38

I'm doing another "portupgrade -rf libxcb" just to be sure, but I've already rebuild wmbluecpu from scratch several times.
Perform 20090123, 20090124 /usr/ports/UPDATING steps.

Install wmbluecpu from ports and execute it.
