Hello Andrew,
when the ODBC driver cannot connect the database I receive an error like:
The driver reported the following diagnostics whilst running SQLDriverConnect
IM002:1:0:[iODBC][Driver Manager]Data source name not found and no default
driver specified. Driver could not be loaded
test.mod:82: error on opening table tb
Model processing error
Assertion failed: count == 0
Error detected in file glplpx17.c at line 1220
Aborted (core dumped)
It is due to a missing xfree.
Please, apply the following patch:
http://glpk.dyndns.org/viewvc/svn/glpk/glpk/branches/glpk-4.31-segmentation_fault/src/glpsql.c?view=diff&r1=290&r2=289&diff_format=h

(see appendix)
Best regards
Xypron
