Follow-up Comment #3, bug #46933 (project octave):

I've tried reproducing this, but can't.

I get the "unsupported type" error (which is easy to fix; just a couple more
lines of CONVERT_CDATA_1 in libinterp/core/graphics.cc), but none of the
octave_value errors, and certainly no crash (segfault or whatever).

When I move the mouse over the figure, I get line upon line of


octave:4> error: unsupported type for cdata (= int16 matrix)
error: parse error
octave:4> error: unsupported type for cdata (= int16 matrix)
error: parse error
octave:4> error: unsupported type for cdata (= int16 matrix)
error: parse error
octave:4> error: unsupported type for cdata (= int16 matrix)


Do you actually get a segmentation fault?

I'd like to fix the parse errors and octave_value errors etc. before "hiding"
them by handling int16 properly.

(file #36187)
