(Most of the time it actually crashed with useless backtrace only starting at handle_fatal_signal, so there seems to be some stack overwrite involved)

The problem affects all of 5.5-10.3, reproducible with the above test case.
On debug builds, this particular crash stopped happening after this commit in 5.5, and merge to higher versions:

MDEV-14786: Server crashes in Item_cond::transform on 2nd execution of SP querying from a view
|
|
MDEV-14957: JOIN::prepare gets unusable "conds" as argument
|
|
Do not touch merged derived (it is irreversible)
|
|
Fix first argument of in_optimizer for calls possible before fix_fields()
|
However, it is not a cure, the same test case still fails on debug builds on all versions, although in a different fashion, possibly the original failure has just been masked:

somehow temporally created item for the view field left in arguments of comparison...
The real problem is that INSERT invalidate re-prepare observer, but it never checked because result returned from QC, then when we start execution without QC we already do not detect need in reprepare (because it was checked before).
Original idea looks like correct, but causes are not found jet:
view field rolled back in other adders:
It used in function constructed for SemiJoin:
(gdb) p args[1]
$2 = (Item *) 0x7fff94027238
(gdb) p args+1
$3 = (Item **) 0x7fff94027438
but rolled back in other address:
T@7 : | | | | | | | info: Rollback: 0x7fff94027238 (0x7fff9400ade8) <- 0x7fff94006c08
i.e. Semi join uses second reference to the field.
in "Normal" execution there is also Item_direct_view_ref used in the right part of semijoin.
but above Items (2 of them created - one during prepare, and one during execution) put in statement memory so they are not removed.
"Normal" execution is based on hack (first bug) that direct view reference put in statement memory and can be used without re-prepare.
It this scenario QC answer instead first execution but statement marked as it was really first time executed (second bug) so direct view reference was put in runtime memory during real first execution and so can not be used after that.
