i686 != x32. Please try the testcase in
https://gcc.gnu.org/bugzilla/attachment.cgi?id=38281
and compile it with -O2 -S:
[hjl@gnu-6 libstdc++-v3]$ ../../gcc/xgcc -B../../gcc/ -O2 -S hash_policy.ii
-mx32
[hjl@gnu-6 libstdc++-v3]$ grep cfi_escape hash_policy.s
.cfi_escape 0x2e,0x10
.cfi_escape 0x2e,0
[hjl@gnu-6 libstdc++-v3]$
