<![if !supportLists]><span style="font-family:"Courier New""><span style="mso-list:Ignore">o<span style="font:7.0pt "Times New Roman"">
</span></span></span><![endif]>from the file name I got a SBCompileUnit<o:p></o:p></p>
<p class="MsoListParagraph" style="margin-left:1.0in;text-indent:-.25in;mso-list:l0 level2 lfo1">
<![if !supportLists]><span style="font-family:"Courier New""><span style="mso-list:Ignore">o<span style="font:7.0pt "Times New Roman"">

<p class="MsoNormal">The problem is that for line 3 in the code below, my SBValue object in the list doesn’t have an address, just “<Invalid stack frame in context for DW_OP_fbreg opcode.>”. Any ideas how to solve this?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Also, how can I set the context for evaluating an expression to a file and line number? (on line 8, evaluate “v” to 1)<o:p></o:p></p>
