The vendored src/vendor/imath/imath.c contains two narrow changes, each marked with a mino: comment for audit on upstream sync:

  • s_realloc casts the unused osize parameter to void to silence -Wunused-parameter warnings when DEBUG is not defined.
  • s_fake takes the absolute value through unsigned arithmetic so negation at MP_SMALL_MIN wraps cleanly in two's complement instead of tripping signed-overflow UB (caught by UBSAN). The fix produces the same result as upstream for all non-MIN inputs, and the documented MIN case now produces the correct unsigned magnitude.

No other changes were made to the upstream source.
