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 e

Answer 1

I ran into this today. Led by Greg Hewgill's answer, I looked at running processes on my system to see if anything was "stuck" or if other users were logged into the machine doing anything with git. I then launched cygwin (installed separately) on this particular machine. It launched ok. I closed it and then tried the Git Extensions again (I was trying a pull operation) and it worked. Not sure if the launching of cygwin cleared something that was shared but this is the first time I ran into this error and this seemed to fix it for me.

Answer 2

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.
