Uninitialized Variable in fastecdsa

Versions of the package fastecdsa before 2.3.2 use an Uninitialized Variable on the stack, via the curvemathmul function in src/curveMath.c, due to being used and interpreted as user-defined type. Depending on the variable's actual value it could be arbitrary free, arbitrary realloc, null pointer...
