This should fix the crashes. The problem I think is that if we abort a syntax parse at some point the parser can leave orphaned functions with LazyScripts around. When debug mode is turned on in the compartment we delazify all functions with lazy scripts, but need to skip over these ones as they don't have any source information --- source info is not set until a lazy script's parent is compiled to bytecode, which never happens for these scripts.

It looks like you have this figured out, but in case it helps I reliably (well, twice) hit this crash at this URL: https://groups.google.com/a/chromium.org/forum/?fromgroups#!forum/chromium-dev https://crash-stats.mozilla.com/report/index/0af49e13-fac3-4db4-86ac-4a2e82130615 https://crash-stats.mozilla.com/report/index/bp-66e2e3d8-42d7-41dc-8d69-4581e2130615

Pushing this ahead of review to fix the crashes; this patch is simple. https://hg.mozilla.org/integration/mozilla-inbound/rev/49b957b9e31b
https://hg.mozilla.org/mozilla-central/rev/49b957b9e31b Should this have a test?

Comment on attachment 763138 [details] [diff] [review] patch Not just aborted-during-parsing, but also self-hested builtins are interpreted-lazy and have fun->lazyScript() == NULL, iirc.
