panic in ServeHTTP: unaligned 64-bit atomic operation

[jmkristian]

WebDAV requests fail with status "500 Internal Server Error". The log (attached) contains "panic in ServeHTTP: "unaligned 64-bit atomic operation".

This seems to be caused by a bug in golang on the armv7l architecture, for example my Raspberry Pi 3. Fixes have been proposed here and here. Some people have worked around it by carefully shuffling field declarations to achieve the required alignment.

I built sftpgo from source code.
$ ./sftpgo -v

Hi,

can you please confirm that it works now? This bug recurs from time to time, I should test at least one 32-bit platform using GitHub actions

It shouldn't happen again in the future
