[Gridflow-dev] most-hated gridflow bugs

I'm sure there are more bugs I hate, but I can't recall them. Listed in
order of hatred (most hated first). Example patches are attached, with
backtraces for the segfaults. My gridflow cvs compile is a month old,
so there is a chance that these bugs are fixed already (apologies, if
they are).
BUG1
[#store] [put_at ...( / [reassign ...( cause segfaults.
BUG2
[#store] sending a badly-dim'd grid to the left inlet causes segfaults.
BUG3
[#out] JPEG fails for large images (I tried but can't reproduce this,
I have not kept the patch that showed the error, so it's likely that it
was something I did wrong...).
BUG4
[#rotate] doesn't work with any type other than int32, and gives an
obscure message that doesn't mention [#rotate] (although the
"find last error" menu item highlights the [#rotate] correctly):
error: ArgumentError: [#inner]: same type please (in has float32\; r has
int32)
base/flow_objects.c.fcs:579:in `void GridInner::grin_0(GridInlet*, int,
Pt<T>) [with T = float32]'
[#inner]
