Hi Jakub,

Thanks a lot for the reduced test case, much appreciated!

This is fixed with 03a70e4c190420e87c0b535285caf8f77260d4ff, which
includes a test inspired by yours.

ecf92194a55188a9c217d76617378749db063453 adds an nghttp2 replacement, as
you suggested on IRC, which is what prompted you to report this bug.
Apparently it works as expected.  Same for 389-ds-base.

Thanks,
Ludo’.
