Inverse trig functions with no arguments crash the calculator #226

Closed dotto44 closed 2 weeks ago

dotto44 commented 1 month ago

Expected behaviour

cos⁻¹ is an invalid expression

Actual behaviour

mate-calc crashes:

munmap_chunk(): invalid pointer
Aborted (core dumped)

Steps to reproduce the behaviour

Install + Open mate-calc
Select mode -> Advanced
Hit "cos", "x⁻¹", "=" A variety of functions work here in place of cos (e.g. any trig function, conj_, Im)

Tangent worked here for invoking the bug, cosine did not, giving an error message about an unknown variable instead. Good enough to test this though
