I should note that I am using python3-3.4.3-6.mga6 on Mageia Linux x86-64 6/Cauldron. |

Pdb says "Running 'cont' or 'step' will restart the program" but it seems to restart on any recognized command other than 'h' and traps everything else. I verified behavior on Win7 with ordinary syntax error 'a = = 1' on installed 2.7.10 and 3.4.3. Removed qualifiers from title. Doc says ''' python3 -m pdb myscript.py When invoked as a script, pdb will automatically enter post-mortem debugging if the program being debugged exits abnormally. After post-mortem debugging (or after normal exit of the program), pdb will restart the program.''' But not being able to exit could not have been the intention. Looking at the code. |
