| VS breaks at line Objects/dictobject.c:2339 - ' if (mp->ma_keys->dk_usable * 3 < other->ma_used * 2)' I don't have any more useful information; I'm running Windows 7. |

| According to IRC log, the issue happens on Windows. And hg revision is a477ef882a16. I'll try building Python on Windows 10 amd64 in this weekend. |

| > VS breaks at line Objects/dictobject.c:2339 - ' if (mp->ma_keys->dk_usable * 3 < other->ma_used * 2)' Can you elaborate? Does the compilation fail? Did you get a crash? What was you doing while getting this error/message? ... Can you please give clues how to reproduce the issue? |

| I compiled, I got a "Python stopped working" during compiling (but it went on anyway), and then launched it from VS in Debugging mode. I did 'from test import support' and then it crashed. VS said this line was the faulty one, and didn't give me anything else useful (no call stack, no access to locals, etc.). I'm sadly not home until Monday, so I can't further investigate this. |

| Emanuel Barry: What is your Visual Studio (exact) version? I know that there are service packs for VS. What is your Windows version? |

| Huh, weird. I'm running a win32 build on a 64 bits machine, with VS2015. I didn't have time to test on a clean checkout, I will do that first thing when I'm back home tonight. I hope I did something wrong and there really isn't any issue :) |

| It's unlikely, but we also print out the UCRT version at the end of the build process (with a warning if you need to update the WinSDK). I built and tested a number of times with this change though. If suggest hg purge and rebuild to make sure everything is clean. |

| I compiled Python in 4 modes: * debug/32 bits * debug/64 bits * release/32 bits * release/64 bits Compilation never fails and test_dict always pass. I'm unable to reproduce the issue, so I removed the "release blocker" flag to not stress our release manager :-) |

| I actually did a clean rebuild and could not reproduce, so I'm guessing something did go wrong on my side. |
