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: # # SIGSEGV (0xb) at pc=0x00007f190120c898, pid=17771, tid=139745381779200 # # JRE version: 6.0_24-b24 # Java VM: OpenJDK 64-Bit Server VM (20.0-b12 mixed mode linux-amd64 compressed oops) # Derivative: IcedTea6 1.11.1 # Distribution: Ubuntu precise (development branch), package 6b24-1.11.1-4ubuntu2 # Problematic frame: # C [libc.so.6+0x7e898]# [ timer expired, abort... ]
Thanks in advance. Kind regards
