This patch set causes a bootstrap failure on AIX:
In file included from /farm/dje/src/src/libgcc/../gcc/unwind-dw2.c:1590:0:
/farm/dje/src/src/libgcc/../gcc/unwind.inc: In function
'_Unwind_RaiseException':
/farm/dje/src/src/libgcc/../gcc/unwind.inc:136:1: internal compiler
error: in maybe_record_trace_start, at dwarf2cfi.c:2433
/* We ought to have the same state incoming to a given trace no
matter how we arrive at the trace. Anything else means we've
got some kind of optimization error. */
gcc_checking_assert (cfi_row_equal_p (cur_row, ti->beg_row));
This is during the stage1 build of libgcc.
