1. When Git PULL gives you this error:

0 [main] us 0 init_cheap: VirtualAlloc pointer is null, Win32 error 487
AllocationBase 0x0, BaseAddress 0x68570000, RegionSize 0x2F0000, State 0x10000
C:\Program Files (x86)\Git\bin\sh.exe: *** Couldn't reserve space for cygwin's heap, Win32     error 0

Answer:

• c:\msysgit\bin>rebase.exe -b 0x50000000 msys-1.0.dll

Or alternatively, do:

C:\Program Files (x86)\Git\bin>rebase.exe -b 0x50000000 msys-1.0.dll

Before you rebase dlls, you should make sure it is not in use:

tasklist /m msys-1.0.dll

If the rebase command fails with something like:

ReBaseImage (msys-1.0.dll) failed with last error = 2 You will need to perform the following steps in order:

1.Copy the dll to another directory 
2.Rebase the copy using the commands above 
3.Replace the original dll with the copy.
