numpy RuntimeWarning with v(int8)

[michaeljpeters]

I'm running into this numpy RuntimeWarning when creating a v(int8) after upgrading numpy to 2.2.4. I think this could be caused by an overflow during negate since the INTS_ is an array of int64.

numpy==2.2.4
frame-fixtures==1.1.0
static-frame==2.18.1

Example:

>>> import frame_fixtures as ff
>>> 
>>> ff.parse(f"s(10,25)|v(int8)|i((IY,ID),(dtY,dtD))|c(IH,(str,int,float))")
/home/peters/.env311/lib/python3.11/site-packages/frame_fixtures/core.py:301: RuntimeWarning: overflow encountered in scalar multiply
  yield v.astype(dtype) * (-1 if v % 3 == 0 else 1)
