I have installed different repositories of OpenSees Libraries on Ubuntu 32bit and 64bit architecture. I have different results when I run the code on 32bit and 64bit machine.
I perform static nonlinear analysis of grillages. I have checked the steps line by line on each platform and unitl I run Analyze(1) the input is the same, but the result of the analyses are different. I compared the result of the 32bit Model with a similar model in SAP2000 and the values are similar, so I presume that something happens on the 64bit platform. The repository that I have been using on 32bit is +/- 5591 (Nov 2013). this version compiles and run on 64bit machines too but gives different results.
I have also downloaded the recent version 5956 and installed it. the C++ program compiles but when I run it I get the following sysmalloc error:
EP_OPS.exe: malloc.c
sysmalloc: Assertion `(old_top == (((mbinptr) (((char *) &((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size) >= (unsigned long)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 *(sizeof(size_t))) - 1)) & ~((2 *(sizeof(size_t))) - 1))) && ((old_top)->size & 0x1) && ((unsigned long) old_end & pagemask) == 0)' failed.[g-Aspire-V5-123:25447] *** Process received signal ***

^Cmpirun: killing job...
with the repository 5956 that error is generated when the program reaches the line where ArcLength Integrator is created (INTEG_2 code lines are below)
AnalysisModel *An_Model = new AnalysisModel();
CTestNormDispIncr *CTEST_2 = new CTestNormDispIncr(1e-6,STEP,0);
EquiSolnAlgo *SOL_ALG = new NewtonRaphson();
StaticIntegrator *INTEG_1 = new LoadControl(1.0,1,0.1,2.0);
StaticIntegrator *INTEG_2 = new ArcLength(1.0);
ConstraintHandler *HANDL = new PlainHandler();
RCM *An_RCM = new RCM();
DOF_Numberer *NUMB = new DOF_Numberer(*An_RCM);
BandGenLinSolver *SOLVER = new BandGenLinLapackSolver();
LinearSOE *L_SOE = new BandGenLinSOE(*SOLVER);
//

Hope you can guide me to fix the issue.
Thank you for your time.
