For one thing, it would be nice if you could give us a pointer to the message. I'm not aware of such a bug report. Also, this is about a non-Cygwin version of git as the path to the git tools suggests. On the other hand, if it's not a Cygwin version, the error message itself only makes marginal sense. So maybe it's a Cygwin DLL as part of some third party package which is often outdated in relation to the official Cygwin distro version. As for the error message itself, it refers to the fact that, after a Cygwin fork() call, the forked child can't reserve the space required for the so-called "cygwin heap", a region used for internal usage especially important for fork/exec related stuff. This usually points to Cygwin DLLs which are not rebased, or a non-Cygwin DLL loaded into a spot required for a Cygwin DLL after a fork. This is especially a problem on 32 bit due to the restricted virtual memory. However, if I'm not completely off-track, the bug report does not really have anything to do with a bad interaction between the W10 console and Cygwin. While my own W10 virtual machine under Qemu/KVM fails to update to versions after build 9926, I didn't encounter any unusual behaviour of the W10 console in comparison with, say, the W8.1 console yet. I'm usually running Cygwin tools in mintty, but I did test the W10 console, too, of course. > Please let me know if there are other problems you are experiencing > with the W10 console that are a regression from previous versions.

We have a regression introduced with Windows 7 and never fixed in W8 or 8.1, albeit I reported it as part of the Windows 7 beta tests. Are you interested to give this a whirl as well?
