testcase with -gnu-tm -O1
I report this bug which is very close to some previous one (PR46269/PR47606).
In this testcase, it fails to detect the block as irrevocable due to the asm
and thus failed in expand_block_tm. Actually the way to mark a block
irrevocable in a transaction_callable is a bit obscure to me.
Thanks.
Patrick Marlier.
