The inline assembly in the routine appears to be fundamentally broken because it manipulates the stack and also tries to take arguments from the stack:
I suspect this only worked in the past because previous versions of GCC may have used %ebp instead of %esp to reference function arguments.

I see a similar problem with the exact same use case.
Disabling the optimization fixes the problem for me too.

Not sure if it is worth to maintain this MMX code and recommend to remove/disable this code from the SDL2.0 codebase for now.

Hello, and sorry if you're getting several copies of this message by email, since we are closing many bugs at once here.
We have decided to mark all SDL 1.2-related bugs as RESOLVED ENDOFLIFE, as we don't intend to work on SDL 1.2 any further, but didn't want to mark a large quantity of bugs as RESOLVED WONTFIX, to clearly show what was left unattended to and make it easily searchable.
Our current focus is on SDL 2.0.
If you are still having problems with an ENDOFLIFE bug, your absolute best option is to move your program to SDL2, as it will likely fix the problem by default, and give you access to modern platforms and tons of super-cool new features.
Failing that, we will accept small patches to fix these issues, and put them in revision control, although we do not intend to do any further official 1.2 releases.
Failing that, please feel free to contact me directly by email (icculus@icculus.org) and we'll try to find some way to help you out of your situation.
Thank you,
--ryan.
