--- Comment #4 from tomas_paukrt at conel dot cz --- I wanted to trace this issue down to the root cause, but the Dart is quite large project and I realy do not have time to isolate the code that triggers this bug and fix it myself, so I just asked for help. The core dump is quite useless as you can see: Core was generated by `/bin/dart bin/run.dart'. Program terminated with signal 6, Aborted. #0 __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51 51 ../sysdeps/unix/sysv/linux/raise.c: No such file or directory. I understand that you do not have such much time too, so lets close this case.
