Comment (by LeadAssimilator):

 Turns out it isn't a crosscompile windows issue, but rather a 32-bit
 compilation issue with gcc.  I've reproduced the issue with master/head on
 Ubuntu 19.10 x64 with gcc 9.2.1-9ubuntu2 by compiling 32-bit ffmpeg using
 the following configure:
 {{{./configure --disable-static --enable-shared --enable-gpl --enable-
 version3 --extra-cflags=-m32 --extra-cxxflags=-m32 --extra-ldflags=-m32}}}

 So far it seems that any 32-bit x86 gcc based builds of ffmpeg have this
 problem, but x64 builds are ok and msvc 32-bit builds are ok.
