I would say that libOSMesa8 had a modification in the list of
exported symbols in the last version.

[TXT]    libOSMesa8-17.3.5-1    21-Feb-2018 09:50     267

I do not see  glBegin in the last cygOSMesa-8.dll of 18.0.1-1
So it seems there is an issue on the last libOSMesa8 package

Indeed, investigating now.


I don't know where your are in your investigation, but I think I found the problem.  The attached patch to the mesa sources seems to fix it

BTW, although the patch suffices to solve the immediate problem, I suspect that there may still be a lot of symbols in the various mesa DLLs that are exported in the autotools build but not in the meson build. Indeed, there are quite a few 'noinst' libraries in Makefile.am files that are not listed in 'link_full' in the meson.build files. If I'm not mistaken, such libraries will be linked with the --whole-archive option in the autotools build but not in the meson build.
