Just to follow up-- The links say that the crash comes from opening a
file with two different versions of a library.  Would it be possible
to get an API entry point to the version the build uses?

It does use the 'fopen' function by name, but not the same version.
And creating the entire object just to get its f_fp field is really
long.
