Try a different program, `mkvinfo.exe` has nothing helpful before the
crash, but `mkvextract.exe` has some things that might be useful. The
first step is some unwinding - bizarrely sjlj (which I thought was
disabled).

Getting to the limit of my skills here, explicitly disabling sjlj in
gcc causes `mkvextract.exe` to crash immediately. Something is likely
throwing an uncaught exception before main.
