darcs apply bundle.dpatch 

fails with the error 'hGetBuf: invalid argument (Invalid argument) for very 
large patch bundle (my patch bundle has 2.1G)

If I send the patch bundle on the standard input to 'darcs apply', everything 

    type bundle.dpatch | darcs apply

I used darcs 12.2.5, 64 bit on Windows 10

Thanks for the bug report.

The sources for 2.12.5 to not contain any call to hGetBuf, so I guess
this comes from a library call.

Can you attach the output of

  darcs apply bundle.dpatch --debug

(might be large, so you should redirect it to a file). Not sure if this
helps but it may give us an idea where to look.

Unfortunately, there is not match in the debug output. It immediately fails with the above error:

    D:\Projects\OPTIMIX\OPTIMIX>darcs apply --debug decompile-produitsimulationdaoimpl.dpatch
    Beginning identifying repository .
    Done identifying repository .
    Identified darcs-2 repo: D:/Projects/OPTIMIX/OPTIMIX
    darcs: D:/Projects/OPTIMIX/OPTIMIX/decompile-produitsimulationdaoimpl.dpatch: hGetBuf: invalid argument (Invalid argument)

The fact that there is not much in the debug output does in fact help.
It clearly shows that the error happens right when the patch bundle is
being read from disk. The function that does this is
Darcs.Util.External.gzFetchFilePS. We have to find out why it fails.
