Assuming that the fonts work fine under Windows, this is indeed very
suspicious.

Please build the library for a different platform, then execute your
program `foo' with

  FT2_DEBUG=any:7 foo

and redirect the output to a file.  Repeat the same on your ARM
platform and compare the results.  This should help find the
problematic spot.

You probably have to provide your own version of `ftdebug.c' in case
environment variables are not supported.

What compiler warnings do you get?

PS: The cmap stuff uses `longjmp' and friends; this could also be a
    source of problems.
