After several false starts (including Windows getting very upset about
*something* to do with moving DLLs around and blue screening on me), I'm
not seeing this behaviour with the 20170606 snapshot.

I have the strace output from both the successful and unsuccessful
cases; the failing case on v2.8.1 appears to be going wrong at the
following exception, which appears to be the first significant
difference between the two strace outputs:

       47  268130 [main] ls 16232 stat_worker: (\??\UNC\<path>, 0x84, 0x180318898), file_attributes 2592
    --- Process 16232, exception c0000005 at 000000018012f3cd

If you can give me your private email address, I'll send the full strace
output over.

Thank you!

Adam
