Bug: SPU Mega doesn't work on Skyrim

[xddxd]

When SPU Mega is enabled on Skyrim, the emulator crashes to desktop when you load into the game.
VS Debugger shows this:

Still present although idk why it matters when default settings work fine.

For what it's worth 2 runs

I got to roam Breezehome but couldn't world gate on the 2nd run.
1st run I get in game for an instant freeze.

I fail to see value in this issue can someone explain?

SPU Block size has no level of accuracy compared to the PS3, since a PS3 doesn't have to recompile code. It's an issue with RPCS3 since ideally bigger block sizes should work with all games and improve performance, I'd say it's valid.

UrbanJP's comment about this issue;
"The only problem is random crashes from entering certain places or playing too long. After I played for around 20 to 60minutes the game would sometimes crash and other times it would be fine. The biggest issue is the random crashes after entering certain places. The ones I've found are House Gray-Mane, Temple of Kynareth, War Maiden's , New Gnisis Cornerclub, and the last portion of Bleak Falls Barrow. The first 3 are in Whiterun, the 4th in Windhelm, and the 5th is a part of the main storyline. If I entered any of these places the game crashed in less than one minute. The only way to get past was to save every 10 seconds and load back in if it crashed. Other than that the game is very much playable if you just really wanted to play it considering it's not mandatory to go to 4 out of the 5 places I mentioned, but it should remain in the ingame category."

@Nekotekina can you fix this one so we can look into defaulting Mega SPU Block Size?

[Nekotekina]

I'll try to reproduce locally

[Nekotekina]

Please try to reproduce with #12684 and show the error message.

[Nekotekina]

It looks like a different issue.

[Darkhost1999]

In that case spu block size Mega is working fine

[Darkhost1999]

Original issue is unobserved in current master
RPCS3.log

I fast traveled, world warped, went in and out of houses, bought and sold items, finished a small errand, returned someone their lost item. And everything all without issue.

@xddxd do you confirm on your side? If anyone else knows games that don't work properly with SPU Mega but work properly with SPU Safe please open a separate ticket

[xddxd]

Still crashes when starting a new game on master. #12684 on first boot it throws
Out of range (in file C:\Users\ContainerAdministrator\AppData\Local\Temp\cirrus-ci-build\rpcs3\Emu\Cell\SPURecompiler.cpp:3093[:20], in function analyse)
If you wait for the modules to compile after the error, on 2nd boot it goes in-game.

@xddxd I updated the PR, another test please.

Verification failed (in file C:\Users\ContainerAdministrator\AppData\Local\Temp\cirrus-ci-build\rpcs3\Emu\Cell\SPURecompiler.cpp:3087[:3], in function analyse)

Probably outdated & fixed, closing. Open a new issue if persists.
