My Windows notebook got updated to Windows 10 and now my Git Bash doesn't
start and when I open an existing repository from Git Gui, I am getting next
error: 
"0 [main] us 0 init_cheap: VirtualAlloc pointer is null, Win32 error 487
AllocationBase 0x0, BaseAddress 0x68570000, RegionSize 0x410000, State
0x10000
C:\Program Files (x86)\Git\bin\sh.exe: *** Couldn't reserve space for
cygwin's heap, Win32 error 0"

I am running GIT version 1.9.5 (latest build for Windows).

Can someone help me?

Thanks for your reply.

Regards,
Michel.

This version is essentially abandoned because the development
happens on packaging the 2.x series for Windows, and using the updated
runtime (MSYS2 instead of MSYS).

So please try this:

1) Fetch the latest version of the new Git for Windows available --
   currently its 2.4.6 RC5 [1].
   Supposedly you should try 64-bit version.

2) If the bug still does manifest itself, prease report it to the
   project's tracker [2].

1. https://github.com/git-for-windows/git/releases/tag/v2.4.6.windows.1
2. https://github.com/git-for-windows/git/issues/

First of all, the home page of Git for Windows has hints where to report bugs (and where to look for possible resolutions first).

Second, this issue is so common that I wrote a wiki page about it: https://github.com/git-for-windows/git/wiki/32-bit-issues

Short version: reinstall Git for Windows. Preferably a 64-bit Git for Windows 2.x from https://git-for-windows.github.io/. And you might want to heed the advice given in http://git-for-windows.github.io/#contribute when you want to report bugs ;-)

Ciao,
Johannes
