I need more detailed information to identify the error; the status code
is not sufficient. Under MS Windows in the case of segmentation fault
(access violation) there should appear an error window indicating some
information, in particular, the module/dll, where the exception
happened, context, fault instruction address, stack dump, etc. Though it
would be better to compile and run glpsol in a debug mode. Please note
that if --check was specified and the model was successfully processed,
the error may happen only in few routines called below a statement
labelled 'done' (see src/glpapi19.c).
