I've managed to rather reliably get DevTools to freeze when compliling to WASM.

Steps to repro:

  • Run devtools with devtools_tool serve --wasm --no-strip-wasm
  • Enable the WASM setting (in the settings dialog), and wait for window to reload
  • Navigate to the Debugger panel, and click on the file name to open the file picker
  • Click another file name in the dropdown to open that file
  • Repeat a few times (rather quickly), eventually DevTools will freeze

Note: I tried to unfreeze DevTools by force-refreshing the page, it took ~minute to reload, and Chrome DevTools console filled up with the following messages:
