Hello, If I test the LuaTeX 0.60 for mingw32 that I can get on http://foundry.supelec.fr/gf/project/luatex/frs/, everything is doing fine, but if I compile my own binary under cygwin, for documents using a lot of big fonts, I easily run out of memory. I don't think it's a big deal as I can use mingw32 binaries under cygwin without any problem, but I think it would be worth documenting it for TeX Live's cygwin distribution (if binaries are built under cygwin). Thank you, -- Elie

Can you check whether this is because of lua garbage collection that kicks in too slow (the most common cause of high memory usage so far)? If this is the cause, then it should be fixable by adding collectgarbage('collect') statements at key points in the lua code that loads those big fonts (one before or after each font should do the trick). But if that doesn't work, then I suspect something is seriously wrong with the cygwin executable and you'll need a tool like valgrind to figure out what is leaking and why. Best wishes, Taco

This does not work, sadly...

Another problem is that Valgrind is not working under cygwin... I won't have time to inquire (especially without any appropriate tool), so I guess the only option is to document it somewhere... Thank you, -- Elie
