New issue 1057: seg fault in particle_deposit.pyx https://bitbucket.org/yt_analysis/yt/issues/1057/seg-fault-in-particle_depos... Brian O'Shea: This script: http://paste.yt-project.org/show/5778/ running on this dataset: http://galactica.pa.msu.edu/~bwoshea/data/datasets/DD0013.tar is causing a segmentation fault in the tip of yt (changeset fffa77d2fdc2) using Cython 0.22 (and 0.22.1). When @ngoldbaum and I tracked it down, it seems to be crashing at line 375 in particle_deposit.pyx , where the value of the variable ii is being set to a large negative number. Note that this bug only seems to occur on some systems - I can get it to happen on my Mac desktop (OS X 10.9.5, LLVM v6) and also a Linux cluster (gcc/4.4.5 and gcc/4.8.3), but Nathan has one machine where it works and one where it doesn't. Nathan will follow this with a stack trace from his gdb bughunt. Responsible: MatthewTurk
