Andi Kleen <andi-gcc at firstfloor dot org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |andi-gcc at firstfloor dot org --- Comment #8 from Andi Kleen <andi-gcc at firstfloor dot org> --- ><source>:3:30: error: cannot tail-call: volatile function type I wonder how that happened. It looks like a bug. volatile functions should be rejected elsewhere and there is no volatile in the test case. Maybe some tree bit encoding gets confused? Should reopen the bug just for this.
