Issue description

After the legal disclaimer ("Notice"), the game will remain at a black screen for around 30 seconds before RetroArch crashes. Seems to crash on Linux as well. Also seems to crash regardless of whether the internal HLE BIOS is being used or the official ones, but I could be wrong.

Step-by-step reproduction and logs

Load the .cue with RetroArch and the PCSX-ReARMed core, wait for the game to load and crash. Tried to produce a log on Windows but it didn't seem very descriptive, but I got this fragment on Linux:

Regular mmap to address 0x10000000 succeeded
Regular mmap to address 0x10200000 succeeded

Memory map is sub-par. Emitted code will be slow.

@pcercuei confirmed. Note this is the demo and not the release version (which works fine), also known as "Gran Turismo (France) (Demo)".

Ok, I can see it. It looks like an issue with the constant propagation mechanism.
