[tlbuild] dvi test?

Following are results from an experiment on three different Macs
(1) macOS 10.13 on Intel (ie High Sierra on a MacBook Pro 17" from 2010)
(2) macOS 11 on Intel (ie Big Sur on a MacBook 12" from 2015)
(3) macOS 12 on ARM (ie Monterey on a MacBook Pro 13" from 2020)
with exactly the same TeX and X11 setup: MacTeX-2020 -- including Ghostscript 9.50 -- and XQuartz 2.8.1.
On all three of them, I typeset t2a.tex and opened t2a.dvi in xdvi, then reloaded page 1.
Short version: no crash on (1), crash on both (2) and (3). Adding -noghostscript to the xdvi call changes nothing.
Longer version: the console output of "xdvi -debug 256 t2a.dvi" is pasted below. I fail to see any logic there.
TeX, Ghostscript and X11 are the same in all cases, so it must come from their environment, whatever this means.
Ghostscript does not seem involved.
The default shell is bash on High Sierra and zsh on Big Sur and Monterey. I ran xdvi in bash on Monterey: same result.
Code signing and notarization are required on Big Sur and Monterey, and not required on High Sierra. Dick (Koch) signs and notarizes all the MacTeX binaries. So it's not that.
SIP (System Integrity Protection) is present in Big Sur and Monterey, absent in High Sierra. But XQuartz reads fonts from /opt/X11/share/{fonts,system_fonts}, where the latter contains symlinks to the System fonts from /System/Library/Fonts (like Times.ttc). The fontconfig files are generated there, not in /System/Library/Fonts which is protected by SIP. So it's not that either.
The only constant in all the tests, I think, is that \usepackage{draftcopy} is required for the crash to occur. So the PostScript instructions in the DVI file,
! userdict
begin
/draftcopy-CurrentPage 0 def
/draftcopy-old-BOPhook { } def
currentdict /bop-hook known{
/draftcopy-old-BOPhook /bop-hook load def
} if
/bop-hook{
draftcopy-old-BOPhook
/draftcopy-CurrentPage draftcopy-CurrentPage 1 add def
draftcopy-CurrentPage 0 ge
draftcopy-CurrentPage 99999 le
and
{ gsave 200 70 translate 65 rotate
/Times-Roman findfont
215 1 mul scalefont setfont
0 0 moveto
0.85 setgray
(DRAFT) show
grestore
} if
} def
end
are responsible for the crash in some way.
I found crash logs xdvi-xaw-<date-and-time>.ips in ~/Library/Logs/DiagnosticReports/, but they are not symbolicated, contrary to John's symbolicated logs earlier in this thread. They tell us nothing beyond xdvi asking for abort(), and the libsystem dylibs obliging.
The only thing I could think of, based on
xdvi-xaw: set_no_char: attempt to set character of unknown font, offset 42
is xdvi excepting a font number in a certain format (integer or non-integer, signed or unsigned, single or double precision -- possibly this makes no sense, I'm speaking here of something, the C language, I don't really know), when processing findfont maybe, and the system libs or frameworks returning this number in a different format.
In the past, when compiling Ghostscript with clang (the macOS compiler), difficulties have arisen at times because of the differences between clang and actual gcc (like clang frowning over implicit type declaration). But these difficulties arose at compile time, not when running the produced binary.
And, above everything, why does the problem arise only when reloading a page, not when loading it the first time?
So I'm absolutely clueless.
