[Switch] possible memory leak leading to crashes

Created by: ms2048

I'm on RetroArch 1.9.0 on Nintendo Switch with newest core available from Core Updater (PUAE 2.6.1 e187a61d). Additionally, I have observed the same behavior in an older build (bundled within RetroArch 1.9.0 for Switch).

To trigger a crash it is enough to just 'Load Core -> Commodore Amiga (P-UAE)', 'Start Core', (wait a few seconds and then enter a RetroArch menu), 'Close Content', 'Load Core -> Commodore Amiga (P-UAE)' (which is NOT the same as 'Start Core') and then it crashes with 'The software was closed because an error occured'. Tried with different cores, games, even quitting and re-launching RetroArch or different homebrew. Tried with fresh config for P-UAE, all sysmodules disabled, etc. and still no deal.

So this looks like some memory leak inside P-UAE.
