The code is valid if you use -fgnu-tm and it works with the C++ front-end too.

Most likely due to this part of the patch from c-typeck.c:
+ else if (TREE_CODE (op0) == INTEGER_CST
+ && maybe_warn_shift_overflow (location, op0, op1)
+ && flag_isoc99)
+ int_const = false;

--- Comment #5 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
The problem is that we're creating a C_MAYBE_CONST_EXPR inside of a
TRANSATION_EXPR, but c_fully_fold doesn't walk into TRANSATION_EXPRs, so the
C_MAYBE_CONST_EXPR leaks into the gimplifier.
__transaction_relaxed
{
<<< Unknown tree: c_maybe_const_expr
8526495038820057088 >>>
}
I don't know if it's OK to fold the insides of a TRANSATION_EXPR. Another
option would to avoid creating C_MAYBE_CONST_EXPRs inside a transaction expr,
like in_late_binary_op?
