[Python-Dev] Re: Jump on C by PyEval_SetTrace Python 3.7.7

Hi. When I changed frame->f_lasti change de code to back, it's work but the line in front code occurs dump, the runtime over. Example: I jump to 8 line and after I jump to line 10, it occurs dump. On python trace pdb the jump works good by the frame-f_lineno. Att.

See: https://github.com/python/cpython/blob/master/Objects/lnotab_notes.txt Good luck ;-) Victor Le lun. 23 mars 2020 à 00:50, Leandro Müller a écrit :

Hi everyone.

I'm trying to make a simple jump on C funcion trace by frame->f_lineno. Example is simple, but not working.

if (frame->f_lineno == 12){

frame->f_lineno = 8;

}

attached files C and python to run test. the line 12 I need to jump to line 8.
