CIS Freezes my PC when run with Open MPI and MinGW

A. THE BUG/ISSUE:CIS freezes my machine

  1. What you did:
    a. Download and install MinGW
    b. Download and extract OpenMpi Open MPI: Version 1.4
    c. Download ans Start CMake and Configure the source
    d. Open a MinGW shell and swith to the OpenMpi source
    e. type “./configure”
    f. System will hang/freeze eventually (when Defence+ is enabled and not in training mode)
  2. What actually happened or you actually saw:
  3. What you expected to happen or see:
    no freeze :slight_smile: → Defence+ Dialog
  4. How you tried to fix it & what happened:
    my system is configured to make it crash (bsod) on the “Strg right+double scroll lock” so i was able to get a minidump (
    If you want a minidump via another method just ask for it (i only know came up with this one method)
  5. If a software compatibility problem have you tried the compatibility fixes (link in format)?:
  6. Details & exact version of any software (execpt CIS) involved (with download link unless malware)
    CIS 5.10.228257.2253, Antivirus DB: 12234
    MinGW current version (i don’t think is should matter though)
    openmpi 1.4 source

Thank you very much for your report in standard format, with all information supplied. (The dump file should list all active processes, so this is not required in this case). The care you have taken is much appreciated by Comodo, and will increase the likelihood that this bug can be fixed.

Just to clarify, I assume that by ‘intelligent’ you mean ‘stateful’

Developers may or may or may not communicate with you in the forum or by PM/IM, depending on time availability and need. Because you have supplied complete information they may be able to replicate and fix the bug without doing so.

Many thanks again

Jeah I do, in the german translation its called “intelligent”

Is this resolved or worked on?

Im asking because I think I get very similar errors when using other programs which are spawning lots of child processes (like cygwin or git), my pc is always freezing in those scenarios, my current workaround is that I disable Antivir and Defence+ (my guess is that Antivir is causing this) in those scenarios.

This is the Fullscreen minidump (Most likely from using git), it is created by the method used above
I did “git svn clone -s .” (svn url changed)

Maybe you should change the title or merge it with exisiting Threads if there are any?
