Hi! And thank you for maintaining many packages!

I've experienced a situation:

Asymptote with option '-tex lualatex' makes an unexpected shift.
(I've installed all the texlive packages by setup*.exe.)

I opened an issue on its main stream https://github.com/vectorgraphics/asymptote/issues/123

But No one seems to reproduce it.
I don't know whether it is an issue only on cygwin or not.

Does anyone have a good idea?


====

Asymptote 2.49 with LuaLaTeX 1.10 as engine on Cygwin makes an unexpected shift.
Is it an issue on Asymptote or on LuaLaTeX?

A test file a.asy:

--------
real s=30;
draw(scale(s)*unitsquare,defaultpen+.5mm);
label("\TeX",scale(s)*(.5,.5));
--------



Compiling as follows results in default.pdf and lualatex.pdf.

--------
asy -f pdf -o default a
asy -f pdf -o lualatex -tex lualatex a
--------

And, default.pdf has no problem, but lualatex.pdf has unexpected shift.

Expected result is
https://github.com/vectorgraphics/asymptote/files/3858069/lualatex.pdf

But what I've got is
https://github.com/vectorgraphics/asymptote/files/3858024/lualatex.pdf


====

I've found that disabling otfload-main.lua (e.g. by renaming it) makes an expected result.
But I don't know why this is effective.

And I really need otfload-main.lua for other purposes.

Please, help me.
