| Summary | 0000343: Fatal crash detected on tutorial './multiphase/twoPhaseEulerFoam/bed' | ||||
| Description | Tested OpenFOAM versions: * OpenFOAM 2.0.x, commit 93ce41240e5c2b04690f15152e52f48e03d4df39, 2011-10-21 11:44:38 * OpenFOAM 2.0.x, commit 03233a7696f077372a090ce1efd19256bbbbf880, Tue Nov 8 12:28:44 2011 While running the whole stock of tutorials in the first commit indicated above, the tutorial './multiphase/twoPhaseEulerFoam/bed' crashed only in some of the following machine scenarios: - 2.0.x 64bit on Ubuntu 11.10 x86_64 with the system's gcc 4.6.1 on a real x86_64 machine - solver crashed. - 2.0.x 64bit on Ubuntu 11.10 x86_64 with the system's gcc 4.6.1 on a virtual x86_64 machine - solver crashed. - 2.0.x 64bit on Ubuntu 10.04 x86_64 with the system's gcc 4.4.3 on a virtual x86_64 machine - solver completed with success. - 2.0.x 32bit on Ubuntu 11.10 x86_64 with the system's gcc 4.6.1 on a real x86_64 machine - solver completed with success. - 2.0.x 32bit on Ubuntu 11.10 i686 with the system's gcc 4.6.1 on a virtual x86_64 machine - solver completed with success.

I tested this on openSUSE 12.1 (gcc 4.6.2 - 64 bit - not virtualized), and I cannot reproduce. The tutorial completes successfully. |

After the "false positive" I had in Issue 344, I made a new test with a clean and fully up-to-date installation of Ubuntu 11.10 x86_64 on a virtual machine with gcc 4.6.1, with a fresh clone with the latest commit: 97fb9ceaefc36d0ba6b5a967a9906bb32c71af76 The result was the same as I initially reported on this report. I'll try installing openSUSE 12.1 x86_64 on a VM next and report back here once more, just in case the problem I'm triggering is either related to my real machine or my VM software. Edit: still on the Ubuntu VM, running directly on the tutorial folder still resulted in the same crash. |

I've now tested this tutorial as well in a VM with openSUSE 12.1 x86_64 with its own gcc 4.6.2 and the tutorial seemed to work fine as well. So, so far the problems I've had have only been with Ubuntu 11.10 x86_64... I think I'm going to also test the development version of Ubuntu 12.04 x86_64, since this might simply be yet another weird issue that I've been having with 11.10... |

Tried and failed to get a development version of 12.04 to work. And ironically, I found out that my personal computer (an AMD 1055T) has gotten a "mild case" of RAM malfunction. So I've redone the test with a fresh new download+install of Ubuntu 11.10 x86_64 on a new virtual machine on a laptop (with an i3 M350 CPU) and downloaded+built the latest commit of OpenFOAM 2.0.x. It still crashes! So far it seems to be a problem isolated to gcc 4.6.1 in Ubuntu 11.10 x86_64. It seems to be a glitch in Ubuntu's stock gcc. Next I'll try with gcc 4.5.3 from Ubuntu 11.10. |

What I wrote on Issue #342, comment #828 also applies here and I quote: «Just finished testing with "gcc version 4.5.4 (Ubuntu/Linaro 4.5.3-9ubuntu1)" on Ubuntu 11.10 x86_64 and it crashed as well. It looks like it's the linker in Ubuntu 11.10 x86_64 that is "damaged". If and when I can test on an alpha release of Ubuntu 12.04 x86_64, I'll report back with more results.» |

I tried on ubuntu11.10 64bit (virtual machine) and cannot repeat the problem but this is with a different (newer) solver. On 2.0.x it seems the unboundedness just gets slightly too large for the solver and this is due to the combination of solver+tutorial. The compiler/machine difference is just enough to push it over the threshold but is not the root of the problem. |

Are you able to reproduce the problem with OpenFOAM-2.1.x? |
|
|
I haven't had the opportunity yet to test with OpenFOAM 2.1.x. I think I can test it this weekend. |
|

I've (also) finished testing this tutorial with OpenFOAM 2.1.x (both binaries and tutorial are from 2.1.x), commit 4bebcad4693c18456a9d3f90f823cd8ee0a36464, using the same virtual machine (without any further updates system-wise) from the comments #829 and #826 and it ran successfully with both gcc 4.5.4 and 4.6.1. I believe you can mark this report as resolved in 2.1.x :) |
