[Bug-glpk] Aborted (core dumped) - when SQLDriverConnect fails

[Xypron]

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
