Comment 4 for bug 1743765

Why would this be a bug in the project and not GCC? Earlier versions of GCC work fine, Keil works fine, I haven't tried IAR but they have a project for that too so I assume it also works fine, the only one with a problem and a 9KB smaller filesize is GCC 7 so I'm more inclined to believe it's a problem with GCC unless shown otherwise.

I've found a workaround to the issue by disabling the link time optimisation flag passed to GCC (-flto), the GCC 7 hex output filesize is now 65KB and the application works
