Re: [libmicrohttpd] 0.9.67 regression

[Christian Grothoff]

Hi Tim,

I cannot reproduce this. We do test for empty body in test_get.c, and
that test passes. I also wrote (and now pushed to master) a
minimal_example_empty.c, using both the 200 and 204 status codes. It
works for me on loopback as well as over the network, using both curl
and wget as clients.

Maybe your issue is about a specific threading mode or something else
you are doing?  Please modify the minimal_example_empty.c to emulate the
situation that is causing the issue.

Thanks!

Christian
