Dynamically linked sparc64 programs reliably fail with an unhandled trap 0x37. qemu m68k reliably segfaults with and without the patch. Again, I tested CRIS and MIPS 8K and they both reliably manage to load and run my programs. I also ran some arm (4K pages) programs, which worked fine.
0x37 is TT_PRIV_ACT, taken when privileged instructions are executed
in unprivileged mode. Could you try running this program again with -d
in_asm,op and see what is the faulting instruction and the generated
ops? Maybe some instruction has too strict checks.
