Well, another, perhaps crude way is like this: add to the function Fdowncase
some simple code which will detect when it is called with the string that
matches "Iosevka", and will call some function, like emacs_abort.  Then you
can put a breakpoint at the line of this call, and when it breaks, see what
the C-level backtrace tells us.

Would you like to try that?  If so, I can help you write that code snippet.

Thanks.
