Sorry, but that is not enough information for us to even give an idea.
It could be a bug in Gecode but also a bug in how you use expressions, whether you have initialized all variables, etc. Can you provide more detail? Best Christian -- Christian Schulte, Professor of Computer Science, KTH, www.ict.kth.se/~cschulte/ From: users-boun...@gecode.org [mailto:users-boun...@gecode.org] On Behalf Of kTorpi Sent: Tuesday, December 03, 2013 2:20 PM To: users@gecode.org Subject: [gecode-users] Segmentation fault while creating an expression Image removed by sender.Dear all, I'm building a model in which I create lot of Vars, and also complex expressions (that actually Vars too) using the minimodel module. Unfortunately after a while I get a segmentation fault from Gecode. The line that causes the fault is Gecode::expr(solver, left + right) where solver is my Space, and left and right are IntVars (IntVar references), which can be also a result of a similar line above, or just simple "leaf" IntVars. And the line from which the segafult comes is support/heap.hpp:554, in which the d pointer seems to be NULL or a wrong address (http://kepfeltoltes.hu/131203/fault_www.kepfeltoltes.hu_.png). Please, could you tell me something about this errors? What could cause it? Am I using Gecode in a wrong way? I use Gecode version 4.2.1 (same thing happens with 4.1.0), g++ 4.7.2, 64 bit linux. Thank you for your help! Steve
