How certain are you it's this specific code snippet that is causing the crash? I don't see anything in it that seems likely to cause a crash or any similar issue. My intuition is that there's a divide by 0 error that occurs in a specific scenario: I realize you are normalizing the velocity vector and have accounted for a v of 0 as a special case; while the overall magnitude is thus never 0, it's possible that up to 2 of the components of v could be 0, so if you are ever dividing anything by those components (in other code I can't see) you could potentially div0 the game.

The only thing that seems potentially suspect is that in MoveSPAS you are destroying the timer twice, flushing the hashtable with the timer's handle after it has already been destroyed, and then (in a very rare circumstance where the bullet hits a target and is also at the end of its travel or is close enough to the ground on the exact same timer tick) potentially destroying the timer a third time and flushing it again. I would consolidate this logic so the full cleanup only ever happens once.
JASS: 
call DestroyTimer( GetExpiredTimer( ) ) //I think this one is meant to be PauseTimer() ?
call FlushChildHashtable( H, GetHandleId( GetExpiredTimer( ) ) )
call DestroyTimer( GetExpiredTimer( ) )

//then below inside the next if-block you have:
call PauseTimer( GetExpiredTimer( ) )
call FlushChildHashtable( H, GetHandleId( GetExpiredTimer( ) ) )
call DestroyTimer( GetExpiredTimer( ) )

I see some other things that could be improved or changed, but these should have no relevance to the crash. Just suggestions:
JASS: 
//the * 1.00 part here is totally unnecessary
set x = x * ( 1.00 / l )
set y = y * ( 1.00 / l )
set z = z * ( 1.00 / l )

//The unit should already have Locust, no? In that case there's no reason to turn off it's pathing since it already has none.
//After adding 'Arav' you can remove it and the unit can still have its fly height manipulated; you don't need to keep 'Arav' on the unit.
//Doesn't matter here but in the case where the unit was intended to be controllable/selectable by the player you wouldn't want to see 'Arav' on it.
call SetUnitPathing( A.dummy, false )
call UnitAddAbility( A.dummy, 'Arav' )

//Strings do not need to be nulled, unless I'm way behind on developments with the string data type. I have a small feeling that
//this could be related to the crash by doing something funky to the string table but I don't know why or have any bigger suggestions.
set WeaponEffect = null
set WeaponEffect2 = null

//Since you're using SPELL_CAST instead of SPELL_EFFECT this event will fire before cooldown/mana cost are used and before any animations finish.
//You start a cooldown so you likely want one, and my guess is that you also want this to happen instantly without delay? There are a few abilities
//in the game that won't interrupt current orders, play an animation, or cause the unit to stop moving which you could use instead.
//The classic one is Berserk.
call BlzStartUnitAbilityCooldown( udg_MainHero[GetConvertedPlayerId(GetTriggerPlayer())], 'A01Z', 0.22 )
call TriggerRegisterAnyUnitEventBJ( t11, EVENT_PLAYER_UNIT_SPELL_CAST )

I made the corrections that were recommended to me but the problem did not disappear, I made the unit shoot for about 15 minutes and the game freezes while about 1000 shots are fired.

It seems to me that the problem is in the timer because the movement function cannot determine the timer that needs to be turned off.
Click to expand...
Why do you suspect that the movement function cant determine the timer that needs to be turned off?

Does the crash occur faster or slower if the shots occur faster or slower? Are the crashes consistent in some way?
