Git Extensions: Win32 error 487: Couldn't rese

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

Just want to share my experience here. I came across the same issue while cross compiling for MTK platform on a Windows 64 bit machine. MinGW and MSYS are involved in the building process and this issue popped up. I solved it by changing the msys-1.0.dll file. Neither rebase.exe nor system reboot worked for me.

Since there is no rebase.exe installed on my computer. I installed cygwin64 and used the rebase.exe inside:

C:\cygwin64\bin\rebase.exe -b 0x50000000 msys-1.0.dll

Though rebasing looked successful, the error remained. Then I ran rebase command inside Cygwin64 terminal and got an error:

$ rebase -b 0x50000000 msys-1.0.dll
rebase: Invalid Baseaddress 0x50000000, must be > 0x200000000

I later tried a couple address but neither of them worked. So I ended up changing the msys-1.0.dll file and it solved the problem.

I have encountered this issue witht he LPCEXpresso building.if you have the C:\MinGW\bin in the PATH. somehow I had to remove it to get rid of this issue since some other MinGW like based too

Answer 3

To fix this issue, I simply let Tortoise Git install its update.

Answer 4

Very simple verison of the rebase solution:

Go to the folder where git is installed, such as:

C:\Program Files (x86)\Git\bin

By holding shift and right clicking in the folder, you should be able to open a command prompt as administrator from there (thanks to https://stackoverflow.com/users/355389/darren-lewis for that comment),

Then run:

rebase.exe -b 0x50000000 msys-1.0.dll

This fixed it for me when the restart approach didn't work.

Hope it helps.

Answer 5

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

Answer 6

If a reboot does not correct the problem (as suggested by Greg Hegwill's answer) then check your PATH for conflicting installation(s) of the msys-1.0.dll (and possibly other related DLLs).

In my particular situation MinGW's installation of msys has a copy of that DLL in its bin directory (<MinGW_Install_Path>\msys\1.0\bin), and it was listed in the PATH. Git's cmd directory was listed in the PATH, but its bin was not. (Git's version of msys-1.0.dll is in the bin directory. Apparently the default installation of MSys-Git does not add its bin to the PATH.)

A temporary fix was to add Git's bin directory to the PATH so that it appears before MinGW's paths. (A more permanent fix will likely involve sorting out the path conflicts between MinGW's msys and Git's and/or removing the duplicate msys installations.)
