[SCIP] Memory Issue

[Stefan Vigerske]

Hi,

SCIP runs out of memory when trying to allocate a big array in 
cons_quadratic, which is used to check whether the coefficient matrix of 
some quadratic constraint is positive semidefinite. You can turn this 
off by setting constraints/quadratic/checkcurvature = FALSE
SCIP should then assume that your quadratic constraint is not convex.
