I am trying to solve an MIP and after presolving, glpk segfaults.
This is what I get even after backtracing:

Constructing initial basis...
Size of triangular part = 5790
Solving LP relaxation...
GLPK Simplex Optimizer, v4.47
5790 rows, 4454 columns, 3571620 non-zeros

Program received signal SIGSEGV, Segmentation fault.
