From the log, it looks like aa['/home/moshe/Desktop/aircrack_dev/src/aireplay-ng']['/bin/dash'] was not initialized using profile_storage() - however I have no idea why.

The only possibly relevant change since r3230 (until r3265) was r3253 ("Fix missing profile init in create_new_profile()"), however what you pasted looks like the /bin/dash child profile already existed, so r3253 shouldn't be relevant to it.

Unfortunately I have no idea what went wrong - from looking at the code, everything looks correct :-/

Can you still reproduce this bug (maybe using a hand-made log entry with profile"/home/moshe/Desktop/aircrack_dev/src/aireplay-ng///bin/dash")? If yes, I'd be interested in the detailed reproducer steps and a copy of the involved profiles.

[Moshe Kaplan (moshekaplan)]

Sorry, I don't have the time to reproduce this bug. :(

[Christian Boltz (cboltz)]

Did you find out how to reproduce this in the meantime? Or was it a strange[tm] one-time crash that never happened again?

[Moshe Kaplan (moshekaplan)]

I never had the time to attempt to attempt to reproduce this crash. Sorry :(

[Christian Boltz (cboltz)]

At least this sounds like it only happened once ;-)

Since I have no idea what caused the crash, I'll close this bug for now.

If you see this or another crash again, please to open a new bugreport (ideally with a reproducer ;-)
