Is this likely a problem with my code or a bug in glpk? Looks to be
reproducible. I can dump more info if needed.
Assertion failed: tcol[csa->p] != 0.0
Error detected in file ..\src\simplex\spydual.c at line 999
/* FIXME: tcol[p] and trow[q] should be close to each other */
xassert(tcol[csa->p] != 0.0);
