Re: [Help-glpk] Strange crash with glpk-java

[David Gabriel]

Hi,

I want to share with new information I get about my crash, this is the message I got:
PATH_TO_JNI/libglpk_java.so.33.0.0(Java_org_gnu_glpk_GLPKJNI_new_1glp_1smcp+0xac)[0x2aaab3c0819a]
Is there any body who can help me to fix it.
NB: I am using glpk in java program

Thanks in advance.

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
