New submission from Xavier de Gaye <xdeg...@gmail.com>: In _PyEval_EvalFrameDefault(), the call to maybe_dtrace_line() sets frame->f_lasti to instr_prev and for that reason, in the ensuing call to maybe_call_line_trace(), the call_trace() function with PyTrace_LINE is not called as it should when a backward jump is not to the first instruction of the line.
