Hi,
There are probably not that many mkii users but just in case you use it
to make something that you include in mkiv / lmtx or similar cases, the
current version of pdftex (tl 2025) has some issue:
\starttext
\startTEXpage
this is a\externalfigure[t:/sources/cow.pdf][height=20pt]cow
\stopTEXpage
\stoptext
Basically anything at the bottom of a tight page setup with no depth, in
the case of text it can be a whatsit, or rule mixed in, spaces don't
matter, will trigger this.
I didn't test your example, but my guess is that is related to the
same issue that I reported yesterday to Thanh and Karl where the
denominator suddenly shifted:
\voffset=-72.27pt
\newbox\sabox
\setbox\sabox\hbox{abc $1 \over 2$ abc}
\setbox\sabox\hbox{\raise\dp\sabox\box\sabox}
\global\pdfpageheight=\dimexpr\ht\sabox %+1pt
\box\sabox
\bye
Mikael told me that there could be an issue so we checked it with
context. It doesn't relate to math at all: any mixed in non-glyphs can
trigger it so it's actually interesting that it didn't show up for mopre
than a year (not seen? not tested?).
We can probably figure out where the issue and fix it but compiling
pdftex is not somthing I want to set up here (and the problem is not
critital enough for context anyway). So it was just a warning. (Also,
adding some 8 sp depth can often be used as workaround.)
