Git Extensions: Win32 error 487: Couldn't reserve space for cygwin's heap, Win32 error 0

Question

Git Extensions: Everything was working fine until yesterday.

But suddenly I am get this error when I try to pull some repositories using git extensions

C:\Program Files\Git\bin\git.exe pull --progress "origin"  Done     0 [main] us 0 init_cheap: VirtualAlloc pointer is null, Win32 error 487 AllocationBase 0x0, BaseAddress 0x68560000, RegionSize 0x390000, State 0x10000 C:\Program Files\Git\bin\sh.exe: *** Couldn't reserve space for cygwin's heap, Win32 error 0 

It is happening for all the repositories which I have cloned. But, my git bash is working fine. I don't have any idea what is going on. Any idea as to why this is happening?

Answer 1

I had the same problem. I found solution here http://jakob.engbloms.se/archives/1403

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

For me solution was slightly different. It was

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 

And make a backup:

copy msys-1.0.dll msys-1.0.dll.bak 

If the rebase command fails with something like:

ReBaseImage (msys-1.0.dll) failed with last error = 6

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.

If any issue run the commands as Administrator
