VM crash when debugging: Unexpected tag 0 (Nothing) in ?, expected a procedure, a constructor or a function node #40916

Open filiph opened 4 years ago

filiph commented 4 years ago

I was debugging a long-running CLI program using IntelliJ. The underlying call looked like this:

$ dart --pause-isolates-on-unhandled-exceptions --enable-asserts --pause_isolates_on_start --enable-vm-service:65514 /full/path/to/program.dart
Observatory listening on http://127.0.0.1:65514/hHNIBgEth-4=/

This program ran for several minutes, then it encountered an exception (which I was waiting for). I started debugging by inspecting variables in the IDE.

Screen Shot 2020-03-06 at 1 48 01 PM

Then, suddenly, the debugging session just crashed. This was the output:

../../runtime/vm/compiler/frontend/kernel_translation_helper.cc: 1936: error: Unexpected tag 0 (Nothing) in ?, expected a procedure, a constructor or a function node
