fvwm-2.6.4 dumps core on 9.0-RELEASE

[WATANABE Kazuhiro]

Hi, all.

I have updated my window manager (x11-wm/fvwm2) from 2.6.3 to 2.6.4.
It compiled on 9.0-RELEASE/i386 with the default option settings.

After the update, fvwm2 crashes randomly and dumps core.
Does anyone have a similar problem?

Here is the stack trace:
