In src/libvx32/openbsd.c:/vxemu_map
int s, sel;
struct vxproc *vxp;
union descriptor desc;
...
/*if(emu->datasel == 0){
if ((s = i386_set_ldt(LDT_AUTO_ALLOC, &desc, 1)) < 0)
return -1; */
emu->datasel = (s<<3) + 4 + 3; // 4=LDT, 3=RPL
if(i386_set_ldt(emu->datasel >> 3, &desc, 1) < 0)
return -1;
...
The s variable is used un-initialized because
of the commented piece of code, causing EINVAL.
And since LDT_AUTO_ALLOC is only on FreeBSD or
Darwin, you're going to have to get it another
way.
At least, that's what I think from reading the
code since I don't have access to an OpenBSD box.
