Maybe not directly related to recent update though...

World and ports built with clang.

When building port everything stop after:

kBuild: Compiling PcBiosBin -

It can sit for hours.

I rebuild devel/dev86 from scratch and replaced /usr/local/bin/as86 with 
unstripped version. Using gcore I catched some cores of running process:

(gdb) bt full
#0  build_number (num=1, width=3, where=0x80587a0 "") at genlist.c:122
No locals.
#1  0x0804d20a in entermac (symptr=Variable "symptr" is not available.
) at macro.c:37
         param1 = Unhandled dwarf expression opcode 0x0
Current language:  auto; currently minimal

diff states that captured cores differ.
