this looks bad as a backtrace (the bp -in parenthesis- goes south). It 
could dbghelp not supporting modules with FPO (frame pointer omission). 
If you recompile wine, could you change the #if 0 in dlls/dbghelp/msc.c 
in function pe_load_debug_directory into a #if 1, and see what gives.
Afterwards, the stack lookup goes wrong, hence the 16 bit addresses.

I'm don't know what goes wrong afterwards after setting the breakpoint 
or not. Even the issues from above shouldn't impact the debuggee.

I'm working on it.
