Hi all,

I am facing strange crash which is not reproducing frequently but I should fix it.
Kindly be informed that the same procedure (where my program crashes) works fine for previous calls (in the same program execution).
I am trying to track the problem, and I find the crash is generated in this instruction :
ret = GLPK.glp_simplex(lpDetourSVNE, parm);
In fact, sometimes my prgram genrates one of these 2 error message:
-1st message:
*** glibc detected *** /usr/lib/jvm/java-6-openjdk-amd64/bin/java: malloc(): memory corruption: 0x00007fb53c024570 ***
-2nd message:
GLPK Simplex Optimizer, v4.47
17 rows, 5 columns, 21 non-zeros
# A fatal error has been detected by the Java Runtime Environment:

Thanks in advance.
Kind regards
