Do you know if there is a workaround we can use for it?

Unfortunately, no.

Also, occurs with Alpine Linux 3.11 (GCC 9.2). I think we will just need to force GCC to use -O0 in debug grades with GCC 9.1 and 9.2. (The bug only seems to be triggered in debug grades.)

We now force the use of gcc -O0 in debug grades with GCC 9.
(Confirmed that installation of the source distribution works with
both Fedora 31 and Alpine Linux 3.11 out of the box.)
