If you've build setup.exe from source using the default make target 
(i.e. 'make' rather than 'make strip' or 'make upx'), then the built 
executable is unstripped and contains symbols (so you don't need the 
.dbg file; which corresponds to a different build in any case...)

gdb setup.exe
run
[reproduce crash]
