Summary 02321: m4clr, m4tst, m4tst2: Screenless systems crash due to problems in some display core functions
Description Run any screenless system in MAME (I only know of these mpu4 test unit, but it probably affect any set with no defined screen), press TAB, enter Video and try to change View from Full to Crop.

MAME crashes with the attached backtrace

 Additionally, I fear there are other core rendering functions which misbehave with screenless systems. If you repeat the procedure above in a screenless system with artwork (it happens in any such a system in MESS; these MAME sets do not have an artwork so you cannot reproduce this part), the exe crashes while rescaling the image

According to Judge: "it scales to infinite width and infinite height"

I leave this note here if Aaron is interested in taking a look to this (since it's however part of the core and could affect later MAME sets)
