New description:

 for current master, if i build on a mac / OSX high sierra environment with
 CC set as any flavor of recent GCC rather than  apple clang, i get a
 failure "no open frame" when as (aka apple clang / apple llvm acting as
 the assembler) is run on the .s file produced by stgRun.c (rts/StgCRun.c
 to be exact)

 this error message seems  to come from https://github.com/llvm-
 mirror/llvm/blob/da4a2839d80ac52958be0129b871beedfe90136e/lib/MC/MCStreamer.cpp#L221

 https://gist.github.com/cartazio/8cbfb3305e1daa4f7ffc3f6bb90a2891 has
 the gcc and clang style assembly for

 /usr/local/bin/gcc-8 -fno-stack-protector -DTABLES_NEXT_TO_CODE -Iincludes
 -Iincludes/dist -Iincludes/dist-derivedconstants/header -Iincludes/dist-
 ghcconstants/header -Irts -Irts/dist/build -Irts/dist/build
 -Irts/dist/build/./autogen -fno-common -U__PIC__ -D__PIC__ -x assembler -c
 /var/folders/py/wgp_hj9d2rl3cx48yym_ynj00000gn/T/ghc22029_0/ghc_1.s -o
 rts/dist/build/StgCRun.debug_o

 this is example asm for the the debug way

Comment:

 or if asm with dwarf as emitted by GCC doesn't play nice with
 (apple?)clang's assembler (which is the system assembler on OSX high
 sierra)
