Description

Game Name?

All (Super Smash Bros. Melee, Super Smash Bros. Brawl, Wii Music, etc.)

Game ID? (right click the game in the game list, Properties, Info tab)

GALE01, RSBE01, R64E01, etc.

What's the problem? Describe what went wrong.

Useless stack dump:

Does not occur when fastmem is disabled. Disabling symbolic breakpoints also prevents the issue from occurring.

What steps will reproduce the problem?

Start any game with Android Studio's debugger attached.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

5.0-13242

Is the issue present in the latest stable version?

Likely. This issue has always been present in Dolphin but disabling symbolic breakpoints is an easy, and somewhat annoying, workaround.

Causing segfaults is the entire point of fastmem. You'll have to work around this in Android Studio if you want to run debugging with fastmem enabled (which I agree is annoying, but there's nothing we can do about it).
