[bug] Stashes lost after out-of-memory situation

[Marek Mrva <mrva@eof-studios.com>]

Hello, hopefully this is the correct mailing list - apologies if it is not.

After issuing "git stash pop" while being low on memory, the following 
was printed to the console:

       0 [main] git 2061 fhandler_disk_file::fixup_mmap_after_fork: 
requested 0x6FFFC1550000 != 0x0 mem alloc base 0x0, state 0x10000,
size 17545957736448, Win32 error 1455
   36836 [main] git 2061 C:\cygwin64\bin\git.exe: *** fatal error in 
forked process - recreate_mmaps_after_fork_failed
   37523 [main] git 2061 cygwin_exception::open_stackdumpfile: Dumping

       0 [main] git 2056 dofork: child -1 - forked process 12100 died 
unexpectedly, retry 0, exit code 0x100, errno 11

Dropped refs/stash@{0} (06d44ccc5ed2ac93b370100f481147ae4f0065db)
error: cannot fork() for rev-parse: Resource temporarily unavailable

Afterwards, the result of "git stash list" is empty, even though there 
used to be more than 10+ stashes saved.

Obviously while being low on memory, one should not expect commands to 
run properly. Losing all the *other* stashes could hopefully be somehow 
avoided, if possible. It is worth mentioning this happened in a cygwin 
environment on Windows.

Any help would be greatly appreciated! :)


With best regards,
