That code is in the RTL, and that may for various reasons not always 
dump correctly.
For me generally it helps, if the rtl itself is recompiled with debug info.

Make sure to use the same kind of debug info stabs="-g -gl" or  
dwarf="-gw -gl" than for the rest of your app, and the LCL,  and all 
included package (so long as packages have dbg info, they do not 
necessarily all need it)

Your 2nd option is to modify the RTL (at the above location), and but 
the stack dupm in there, before the exception is raised....
