Yeah that was pretty dumb- I guess I was a little overworked there, sorry.
The original non-simplified version didn't work for unrelated reasons: It
appears that a missing in a struct full of function pointers seemed to throw
off the memory addresses, causing some random address to be called, that by
coincidence contained something that didn't do anything.
# bad
type
foo* {.bycopy.} = object
bar*: proc ()
fuz*: proc () # calling fooObject.fuz() points to the wrong address,
either crashing or calling something else
# good
type
foo* {.bycopy.} = object
bar*: proc () {.cdecl.}
fuz*: proc () {.cdecl.} # this works
Then I simplified the thing and behaved the same, so...
For posterity, part of what I was missing was how to print function pointer
addresses:
# echo function pointer from struct passed from C++
echo "fooObject.fuz: ", cast[cint](fooObject.fuz)
