Description Andi McClure 2016-12-15 20:50:47 UTC
When scanning the registers+stack for an SGEN collection, we do not scan the FPU registers on Linux for ARM in C9.

We have a fix for this in C10 ( https://github.com/mono/mono/pull/4127 ) but it has not been backported.

Because this creates high risk for hard-to-spot bugs it should be fixed for C9.

This was backported some time ago:
