Hey @mossmaurice, thanks for reporting this issue. This is caused by a compiler bug found in GCC 9.1.0 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90736) and is already fixed in GCC 9.2 and above. The solution here would be to not use GCC 9.1.0 and instead use GCC 5 or above.

I would close the bug for now since this would be some effort to circumvent this already fixed compiler bug. If it stays an issue then please report the bug again with a short reasoning why the broken GCC 9.1.0 version should be supported.
