Arch +1 +1

I can confirm with git builds of DWM, and ST opening ST via ALT+SHIFT+ENTER causes problems when quiting X.  Rebuilding with termcmd set to open xterm works fine, xserver closes normally. Opening ST via Dmenu works fine. I dont think the problem is with DWM, or it is its been a long standing bug, even the 6.0 release of DWM that arch has in ABS has the same problems with ST.

Dmesg shows a kernel opps when closing DWM after at some point opening ST:
