I think I just found the problem: I thought that h2_h2.c, line 678 was no longer needed. But under some, still unknown, conditions the post_read_req hook is called twice. That makes a table overlay twice which results in all headers_out be present twice.
I will remove the filter again before installing it. Someday, I need to understand the double invocation of the hook... //Stefan > Am 07.12.2015 um 13:38 schrieb Jim Jagielski <j...@jagunet.com>: > > Can you retry w DEBUG level, to see if h2_response_trailers_filter() > is the issue? > >> On Dec 6, 2015, at 6:33 AM, Jan Ehrhardt <php...@ehrhardt.nl> wrote: >> >> Stefan Eissing in gmane.comp.apache.devel (Sun, 6 Dec 2015 09:26:56 +0100): >>> Jan, thanks for tracking this down to the duplicate headers.
