This only happens with the new --cpu-mode=1 option.

Environment:
32-bit Ubuntu 12.04 LTS
2.0 GiB RAM
Intel Centrino Duo T2300 @ 1.66 GHz x 2
GeForce Go 7400/PCIe/SSE2

Steps taken:
1. Build from SourceForge source download
2. Run desmume as "desmume --cpu-mode=1"
3. Select a game using the GUI or Recent Files
4. DeSmuMe spams console and crashes
5. Run without --cpu-mode; does not crash

Terminal Output: http://paste.ubuntu.com/5672464/

    I have similar situation, Linux (Fedora 18), compiled from 0.99 source
    It produced something very similar to this article: http://forums.desmume.org/viewtopic.php?pid=21183
    desmume: arm_jit.cpp:3939: void sync_r15(u32, bool, bool): Assertion `!instr_uses_r15(opcode)' failed.

    So I added "#define NDEBUG" in arm_jit.h and recompiled,
    this time i get almost identical result with the original post: WRONG MODE spamming and segfault.

    1) How do I save (state) in this situation? none of my roms start at all so I dont get any screen or menus

    2) Any other information you need that I can produce?

    Cannot get savestate, since desmume dies before

    Reproduced on x86_32 linux but not on x86_64. Diagnosed as calling convention (which explains the OS dependence). Fixed in [r4728].
