Re: [mbed-tls] Failures: all_sh-ubuntu-16.04-test_memory_buffer_allocator - mbed-tls

18 Feb 2021


      Hi Gábor,
To reproduce locally, the correct invocation would be
tests/scripts/all.sh test_memory_buffer_allocator
Specifically, the failing tests are SSL tests. To reproduce those tests,
build the right configuration and run
tests/ssl-opt.sh -f 'DTLS fragmenting: proxy MTU, * renego'
I've posted the relevant logs on the GitHub issue.
It's unusual for the memory_buffer tests to fail when memory sanitizers
are passing, so I don't know what's going on.
