3Just a couple of useful windbg commands:
4
5Show python filenames + frame line number (not statement) up the call stack:
6!for_each_frame ".block { dt python27!_frame qwo(!f) f_lineno; da qwo(qwo(qwo(!f)+0x20) + 50) + 20 } "
7
8Same, alternative version:
9!for_each_frame .if ( $spat("${@#FunctionName}","*PyEval_EvalFrameEx*") ) { .printf "python frame: line %d\npython frame: filename %ma\n", @@c++(f->f_lineno), qwo(qwo(qwo(!f)+0x20) + 50) + 20 }
