Description

When playing the attached .spc file (from Super Famicompo 3) in audacious-git (d32136dac2c6ad26e52babf468e3ca63152d8a73), Audacious crashes with message:

audacious: Spc_Cpu.cc:498: int Snes_Spc::cpu_read(int, Snes_Spc::rel_time_t): Assertion `reg + (r_t0out + 0xF0 - 0x10000) < 0x100' failed.

The failed assertion is at https://github.com/audacious-media-player/audacious-plugins/blob/22a0c2d7f353e5f1312632d107cb053fca4dc8c1/src/console/Spc_Cpu.cc#L498.

mpyne's libgme has the same assertion at https://bitbucket.org/mpyne/game-music-emu/src/b3d158a30492181fd7c38ef795c8d4dcfd77eaa9/gme/Spc_Cpu.cpp#lines-482.

kode54's libgme uses Higan's S-SMP and doesn't contain Blargg's Spc_Cpu.{cpp,cc}: https://bitbucket.org/losnoco/game_music_emu/src/master/gme/higan/

Blargg's CPU emulator is... less than secure (https://scarybeastsecurity.blogspot.com/2016/12/redux-compromising-linux-using-snes.html), though Audacious's copy has been patched. I didn't look into how to resolve this assertion error though.
