cannot step by instruction in dbx/mdb inside guest

[Lubos Kosco]

64bit host OpenSolaris 09/06 (on x2250) + vbox 3.1.0 from extra repository happens in 64 bit guests nv129 & OpenSolaris 09/06 , NAT

I ssh through a forwarded port to the machine & I do

$ mdb /usr/bin/ls

main::bp ::run ::step

mdb: target stopped at: main+4: pushl %esi

::step

mdb: target stopped at: main+0xc: xorl %ebx,%ebx

main::dis

main: pushl %ebp main+1: movl %esp,%ebp main+3: pushl %ebx main+4: pushl %esi main+5: pushl %edi main+6: subl $0x2bc,%esp main+0xc: xorl %ebx,%ebx main+0xe: movl %ebx,0xfffffd74(%ebp)

as you can see the step command skipped more than one instruction same thing is happening for dbx

I am not sure if this is a bug of emulation or mdb/dbx, hence this bug ;)

thanks much for clearing it up for me
