--- Comment #2 from Eli Friedman <efrie...@quicinc.com> ---
In C, it is only legal to access a variable while it's live. (From the
standard: "its lifetime extends from entry into the block with which it is
associated until execution of that block ends in any way".) The code in your
testcase declares a variable inside a block, then tries to access it after the
block exits.
Of course, statement expressions aren't part of the standard, but I can't think
of any reason why we would treat them differently from regular blocks in this
context.
