Re: Someone using COMPAT_SVR4(_32) ?

Martin,

6.0.6 sparc64, 6.1.5 sparc64, 7.1 sparc64 (all GENERIC), fail with the same
behavior (meaning, same ktrace ouput) given the same payload (sparc
solaris 2.6), ktrace shows:

[...]
  1119      1 k        CALL  mmap(0x2000,0x80000002,0,0x45f,2,0)
  1119      1 k        RET   mmap 1074167808/0x40068000
  1119      1 k        PSIG  SIGSEGV SIG_DFL: code=SEGV_MAPERR,
addr=0x0, trap=48)
