I am using GLPK version 4.17 as a multi-threaded DLL compiled with visual studio 2005 for windows (version VC8). GLPK is used in a column generation algorithm. Multiple iterations of adding some columns, solving LP, retrieving primal and dual variable information. For problem sizes around 3500 columns the DLL crashes with a stack overflow error. The error occurs in the retrieval routines after the lpx_simplex function has successfully completed, typically in get_col_prim or get_col_dual. Small problem instances are solved correctly. Is this a bug or an inherent limitation. Can the limitation be circumvented?
