Ah. I should have caught that, sorry. I wonder if the patching needed here and elsewhere for amsmath could instead by taken up by amsmath itself... (for some reason I thought David tried to do that at some stage, but I guess not).
I'm certainly keen to incorporate amsmath patches from unicode-math and lualatextex-math.sty into amsmath, not so sure about breqn/flexisym which seem rather more experimental...
What should I do if I encounter this error?
flexisym tries to patch the
\@begindocumenthook
by using some commands as marker:This breaks now if a user uses it together with unicode-math:
