Bug Description

The libssh 0.9 armhf eoan tests are failing
http://autopkgtest.ubuntu.com/packages/libs/libssh/eoan/armhf

The error is
'disInstr(thumb): unhandled instruction: 0xEBAD 0x1CCA
==1127== valgrind: Unrecognised instruction at address 0x4b9c93d.
==1127== at 0x4B9C93C: ??? (in /usr/lib/arm-linux-gnueabihf/libcrypto.so.1.1)'

Looking upstream to valgrind bug there is one matching with an (unreviewed) patch

It's unclear to me why that only started to me a problem but if it can be fixed from the valgrind side that would make sense, could foundations look if that patch makes sense/could be applied to the Ubuntu package maybe?

The regression appears to be caused by a change in libssl, not in libssh or valgrind, therefore the autopkgtest regression is already present in the release pocket and the failure should be marked as a bad test.

oh, except not exactly due to a change in libssl, because in the same time period, libssh 0.8.7-1 autopkgtests still pass and libssh 0.9.0-1 fail. Still looking.

I can confirm that the referenced upstream patch fixes the autopkgtest failure.
