Hi, I am testing trunk on darwin14 (Mac OS X Yosemite), and I am seeing a lot of (800 so far) C++ failures, in the form of internal compiler errors, like this:
> vbase1.C:17:1: error: unrecognizable insn:
> }
> ^
> (call_insn/j 4 3 5 (call (mem/u/c:DI (const:DI (unspec:DI [

> <function_decl 0x143563d80 __comp_dtor >)
> ] UNSPEC_GOTPCREL)) [0 S8 A8])
> (const_int 0 [0])) vbase1.C:9 -1
> (nil)
> (nil))
> vbase1.C:17:1: internal compiler error: in insn_default_length, at
> config/i386/i386.md:2071
Google and bugzilla search don’t find anything particularly recent like that,
but the scale of it is weird. I have isolated a very small reproducer, attached
(gives the above ICE with no compile options).
Has anyone seen this on another platform? Is it known? Otherwise, I’ll report
it.
