Crash on Load amd

[Savotu1]

I did post this in #103 as I am having the same problems but Tarik02 has closed the issue so thought I would post my own.

I am using the updated master branch and getting Signal 11 received when running with or without --amd-fix.

When running through Valgrind without the amd fix everything works but is so slow just getting from one screen to another takes a long while.

./mcpelauncher --help advises to use --amd-workaround which is another bug as the correct command is ./mcpelauncher --amd-fix

My valgrind output with the amd fix is below

Hi, don't do --amd-workaround and then post the log again.

[Savotu1]

Hi,

Without the amd fix gdb pshufb as being the issue.

Here is the log without the amd flag

log.txt

sorry about the upload its very long

[Savotu1]

After a clean build and first run gdb says that the illegal instruction is pshufb

When you run with valgrind the game runs but very slow and is not playable.

Checking again with gdb at this time shows the illegal instruction is 0xec6ee725 phaddd %xmm3,%xmm3

Not sure if that helps or not, i know that phaddd is another ssse3 instruction which my cpu does not support, maybe you can add another workaround for that?

If you need any other logs just let me know.

Just wanted to add that i can copy the whole dir to an Intel laptop and everything just works with out a recompile.

I found this intel-software-development-emulator no install needed just

../sde-external-8.12.0-2017-10-23-lin/sde -- ./mcpelauncher

It does not need installing and for me allows the game to run, loading is very slow however the game runs fine.

[MCMrARM]

Now, that I think of it: What CPU exactly do you use? (This is a question to everyone who has an Illegal instruction crash that does not happen on startup but later)

I might have an idea on how to implement this & fix it permanently.

AMD Athlon(tm) II X2 255 Processor is my cpu

[HybridZach]

AMD Athlon(tm) II X3 450 Processor Running with the intel-software-development-emulator It crashes with this error...

If someone could help me run it with the ISDE and GDB so I can show you more, never used gdb before.
