The crash error was:
dwm: fatal error: request code=12, error code=11
X Error of failed request: BadAlloc (insufficient resources for operation)
Major opcode of failed request: 12 (X_ConfigureWindow)
Serial number of failed request: 3333
Current serial number in output stream: 3338
This was backtracked to function updatesystray where XConfigureWindow was
called with large negative X positions (e.g. -836585). The large number
coming from the width of the systray icon.
w += i->w;
The systray icon width is set through the updatesystrayicongeom function
and this is called by resizerequest, clientmessage and propertynotify.
The height and width would appear to come from the X window attributes and
sometimes have random values (e.g. height 32708 and width 1369918222).
updatesystrayicongeom restricts the height of the icon to that of the bar,
but did not have any restictions on the icon width. This fix limits the
icon width to that of the bar height if it is greater than twice the bar
height, leaving room for systray icons that are slightly wider than they
are tall.
Text from original patch:
Using pango markup for status text
Use a single font. Removed some code utf8 code from drw.
Created for pango 1.44. Older versions might not have getter
for font height, ascent + descent can be used instead.
All texts are rendered with pango but only status is with
markup. Increased stext size (in case a lot of markup is used).
MIN/MAX is already defined (didn't redefine them).
Text width calculations when using status2d strings resulted in
statuscmd button placement calculations to be way off. Fixed by
introducing a separate function status2dtextlength to get an
approximate correct text width.
