GameCube emulator periodically crashes about 5 seconds after starting - "stack smashing detected"

[jp123]

It will work fine for hours, playing any game. Then, some time later if you try to play another game or the same game, it will display the start screen and then quit after several seconds, back to Emulation Station.

I have found that if it doesn't crash within the first five to ten seconds, it won't crash at all.

In the logs, I get the message "stack smashing detected" (below).

The two times that I have gotten it to "work" again were when I tried renaming one of the memory card files (not sure if that did anything), and when I tried enabling logging in the dolphin-emu, hoping to catch an error message, after which it started the game perfectly. Although, subsequent trials had the same issue of quitting after a few seconds (and with nothing meaningful in the logs). I don't think either of these actions actually had any direct effect, but I am wondering if the act of changing something about dolphin-emu had some indirect effect?

I will also note that doing the following

# export DISPLAY=:0.0
# XDG_CONFIG_HOME=/recalbox/share/system/configs XDG_DATA_HOME=/recalbox/share/saves /usr/bin/dolphin-emu-nogui -e "/recalbox/share/roms/gamecube/All Games/Super Smash Bros. Melee (Europe) (En,Fr,De,Es,It).iso"

seems to work consistently without issue.

I do get these following messages when I run the above (no-gui) command:

12:38:353 PowerPC/SignatureDB.cpp:124 E[HLE]: Wrong size! Found __DBExceptionDestination at 80336234 (size: 0000002c instead of 00000010)!

and:

12:39:727 BPStructs.cpp:684 W[Video]: Unknown BP opcode: address = 0x00000046 value = 0x0000024c

but, I wonder if those are normal?
