Ran into an ice today while attempting a profiled bootstrap of mainline:

/> gcc -c -O2 -fprofile-use -freorder-blocks-and-partition dwarf2out.i
dwarf2out.c: In function âoutput_call_frame_infoâ:
dwarf2out.c:2410: internal compiler error: in make_edges, at cfgbuild.c:350
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

I'll attach .i, .gcda, and .gcno files
