TortoiseGit + Cygwin git: unified diff fails (cygheap read copy failed)

Hey everybody!

I'm using TortoiseGit with Cygwin git (Cygwin workarounds enabled in
advanced TortoiseGit settings). For the most part, everything works
The only problem: in TortoiseGit log for any repository, right-click
any commit, pick "show changes as unified diff", there's an error

Could not get unified diff.
   1 [main] git 2292 child_copy: cygheap read copy failed,
0x180302408..0x18030F230, done 0, windows pid 2292, Win32 error 6
411 [main] git 2292 C:\cygwin\bin\git.exe: *** fatal error - ccalloc
would have returned NULL

Actually I've had this several months ago, just never got around to
posting this to the list.

Cygwin 64-bit 2.876
Cygwin git 2.8.3-1
Windows 7 x64

Appreciate any help!
