Sorry, but I wasn’t able to reproduce this (streaming any of "client-request-1”
through "client-request-5”).
Note that - using your patched “config.linux” configuration file - I get a link
error:
/usr/bin/ld: cannot find
/usr/lib64/clang/11.1.0/lib/linux/libclang_rt.asan-x86_64.a: No such file or
directory
However, I was able to use the "config.linux-gdb-sanitize” configuration file
(introduced in the last LIVE555 release), running
./genMakefles linux-gdb-sanitize
This let me build “testOnDemandRTSPServer” (after applying your patch to
“RTSPServer.cpp”), but I didn’t see any errors (again, with any of the
“client-request-*” files).
Also, the file "bug-report.txt” in your attachment refers to a
"heap-use-after-free” error, not a “stack use after return” error. And it
appears to be referring to an old version of the LIVE555 code, not the latest
version (2023.06.14).
I’m going to need to see more evidence that there’s a real error here.
