Let's adjust the test a bit: % cat fadvice_bug.c #define _GNU_SOURCE #include #include int main() { int fd =3D open("/etc/passwd", O_RDONLY); assert(fd > 0); posix_fadvise(fd, 0, 0, -1); return 0; } % /compat/linux/bin/gcc -m64 fadvice_bug.c -o fadvice_bug64 % truss ./fadvice_bug64 ... linux_fadvise64(0x3,0x0,0x0,0xffffffffffffffff) ERR#-22 'Invalid argument' ... % /compat/linux/bin/gcc -m32 fadvice_bug.c -o fadvice_bug32 % truss ./fadvice_bug32 ... linux_fadvise64(0x3,0x0,0x0,0x0) =3D 0 (0x0) ... > amd64's 32-bit Linux syscall definition for fadvise64 looks right. That's the weird part. It looks right to me as well, at least at first sigh= t. --=20 You are receiving this mail because: You are the assignee for the bug.=
