With gcc 7.2 all projects that useasm volatile can't be compiled any more.

Is there a work around?

From the issue title it sounds like some very specific asm volatile is causing the issue. Why does the code clobber r2? Does it need to be PIC?

It seems a bad idea to use PIC register clobbered... and starting from gcc 7 it's not permiited any more....
