------- Additional Comments From alex.cherepanov at artifex.com  2008-07-29 12:20 -------
The patch from the comment #2 is committed as a rev. 8901.
Even if NULL pointers to structures are invalid, a crash in execstack
is clearly undesirable.

This patch is similar to a protection measure in modern printf(),
which prints NULL instead of crashing when it receives NULL pointer.

Besides, NULL is a valid pointer value in C and it should be possible
to pass it through PostScript level and expect that it is compatible
with the error handler.
