If I get this right, there is an element in elts, that has a valid string key ("H2_STREAM_ID") bis a NULL value (2nd screenshot) and the condition check in line 527 of the first screen shot checks key against NULL and empty, but value only against empty but not against NULL. So the empty check

Just to confirm: Did you build the r1874909 just like the other releases you tested or did you use the already built 2.4.43 that crashed originally? (I know these should all be the same, but I want to make sure that we are not looking at some strange side effect.) Thanks, Stefan > Am

Assuming this happens really in thread start of a HTTP/2 worker, the following change was made in Revision 1874909. The stacktrace indicates a 64 bit system. Is someone making assumptions about connection->id content here? winnt mpm? Another module that freaks out? Or do I just not see the

Thanks Rainer, All clean build using the released sources, so a clean build of httpd 2.4.43 GA gives the crash. What header file is Stefan referring ? On Tuesday 14/04/2020 at 11:06, Rainer Jung wrote: Hi Stefen, I think Stefan refers to his "somehow was partially using the old

Sorry, that was a bit to fast: looking at the revision, he references file modules/http2/h2_bucket_beam.h But in that revision the change was the removal of a struct member at the end of the struct. I don't see, how that could lead to a crash in case an old header file was used, that would

Hi Stefen, I think Stefan refers to his "somehow was partially using the old header file". So during the build, there should be no other (from other versions) header files from APR, APR-UTIL oder HTTPD anywhere on the build system where the build process might find and use them. He was

Re: mod_http2 crashes libhttpd.dll in 2.4.43

In that revision, I see a change in the header file structure. If your build of r1874909 is not clean but somehow was partially using the old header file, things might get misaligned. The other changes in that revision look rather unsuspicious to me. Steffen: could you make a clean rebuild of
