Hello Luigi,

There is no message, luatex just hangs... (no cpu usage).

I switched from mingw to cygwin some time ago for several reasons.
The one I remember: a lot of packages are easily available for cygwin but not
for mingw.

Yes.


New results:

I've built luatex under cygwin and replaced luatex.exe in my windows
installation. Now it creates a pdf, but there is a stack-dump in the end:

This is file luatex.exe.stackdump:

Here a new example file for easy testing:

\startbuffer[testmod.c]
#include "lua.h"
#include "lauxlib.h"
static int l_test(lua_State *L)
{
		int n = luaL_checknumber(L, 1) * 100;
		lua_pushnumber(L, n);
		return 1;
}
static const struct luaL_Reg mylib[] = {{"test100", l_test}, {NULL, NULL}};
int luaopen_testmod(lua_State *L)
{
		luaL_register(L, "testmod", mylib);
		return 1;
}
\stopbuffer
\startbuffer[Makefile]
testmod.so: testmod.c
			gcc -shared -o $@ $< /usr/lib/liblua.dll.a
\stopbuffer
\savebuffer[testmod.c][testmod.c]
\savebuffer[Makefile][Makefile]
\executesystemcommand{make testmod.so}
\startluacode
package.cpath = "?.so"
require("testmod")

\starttext
