I've got a problem with the previous version 0.2.8 on -current: dynamips crashes when it tried to start router emulation with message "bus error (core dump)". Then I've tried to upgrade it to 0.2.10 but I've got the same error. I didn't have 9.x right now for testing it compiled with gcc (clang problem?). By the way, here is the patch for upgrading it 0.2.10 in case it works on Fix: Patch attached with submission follows: How-To-Repeat: just start dynamips on a recent -current.

Hi, It seems that "some" file-targeted printf end up in coredump. (I say "some" because first few succeeds without clear reason. Ie: first few logs work (and end up in the file) then one makes dumping guts also without good reason) Removing logs from source allows the emulator to run until it hits another log.

FYI: - Same problem with A) System 10-BETA1 B) compilation with gcc46 - Confirmed dynamips works on 9.1 amd64.
Hello. Compile dynamips without JIT support solved this problem.
what is the status of this PR? Should it be closed? I can't tell if there is still a problem or not.
No feedback, so I'm closing the PR.
