I am going to assume that you are correct about the the byte offset. I
had vague recollection of this being mentioned before on the mailing
list, but did not encounter it until now.
The very benign seeming changeset at
https://foss.heptapod.net/graphicsmagick/graphicsmagick/-/commit/7ff15be04d174ccdeea0004ffa4a45dd4a9e81aa
(see only configure.ac) triggered it.
Running the configure script directly using bash or exporting
'CONFIG_SHELL=/usr/bin/bash' allows configure to succeed.
I will take this as the opportunity to simply remove the archaic feature
(Display Postscript) I re-enabled with the changeset since I have not
encountered a system with it for a great many years.
That also would explain why an older GraphicsMagick doesn't see the
problem: the line in question happens to not appear exactly at a
buffer boundary.
Bad luck!
Of course I'm just guessing.
Good guess. Thank you for your help.
Hopefully a future stable Autoconf will detect the broken shell and set
CONFIG_SHELL=/usr/bin/bash in order to succeed.
