Hi folks,
I've got a problem with fvwm on Linux (current snapshot as well
as fvwm-2.5.24):
run "xine" (without arguments)
right click on the movie window
select Settings --> Setup
select the "video" tab
select the "video driver to use" drop down menu
scroll to the end and select the last entry
After that fvwm used up a complete CPU (100%). A backtrace showed
where it got stuck:

events.c is something fragile, AFAICS, so I tried it with
#undef EXPERIMENTAL_ANTI_RACE_CONDITION_CODE
Now the bt showed:

This was generated using the snapshot of today (20080818). Distro
is Debian (amd64) on a Core2 Duo.
Can anybody reproduce this?
