@emersion the actual instruction is:

(gdb) x/i $pc
=> 0x564b24191e32 <get_deco_rect+354>:  idivl  0x4(%rsi)

However I can only assume this is because the optimisation has moved things around.

I think this is a duplicate of #3870. Unfortunately, this was fixed after the 1.0 release, but is fixed on git master

@RedSoxFan it looks like.. I'll update to the -9999 build until 1.1 makes it's way to the repos. Thanks.
