FreeType function table messed up.

[Max Savenkov]

I have compiled FreeType into JavaScript using vs-tool/Visual Studio 2010, and linked my program with it. But during runtime, in one of the calls inside library, functions table seems to be messed up - instead of proper FreeType function, unrelated function from another library gets called. It seems that this is a linking problem. How do I debug this?

My current setup is as follows:
1) Compile FreeType 2.5.3 in Visual Studio 2010, producing libfreetype.bc, rename it to libfreetype.so to satisfy CMake
2) Compile Allegro library, which uses FreeType (liballegro_monolith-debug.so)
3) Compile my project, spefiying -lallegro_monolith-debug and -lfreetype

I'm using Emscripten SDK v1.16.0. Most of FreeType works, surprisingly, but because this single call gone awry, I'm can't specify fonts size - FreeType renders them all in default size :)

Have a look at this change: https://github.com/juj/emscripten-freetype/commit/6b415373577fef697fd2ad6472939eb221d64a13 . Does that help?

Yes, that did help, thank you! Unfortunately, it seems like this patch hasn't made it into FreeType 2.5.3 at least, and it is no longer correct in two places.
For anyone who has to apply it by hand to 2.5.3 version, here's what needs to be changed:

1) cid_parse_font_matrix now has two more places where error value is returned. Since this function actually needs to be void, you'll have to change them to "return;" too.
2) af_dummy_hints_apply, the 3rd param no longer has type AF_ScriptMetrics, but rather AF_StyleMetrics.
