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

hmm and I just noticed this silly wiki broke all new lines, hopefully you can decode it, if not I can repaste and somehow make the lines visible (code block?)

The Wiki isn't silly but there is a help and there is a preview button.
