core dump on exception exit when attempting to redefine 'module'
Closed this issue · 9 comments
GoogleCodeExporter commented
Hello,
a core dump occurs when something like the following occurs:
QUnit = require('..../qunit.js').QUnit;
module = QUnit.module;
module('foo');
I'm not sure if that will do it however, I can't quite make a reduced test
case. However it is 100%
reproducable. I can make a debug version of gpsee and re-core, if this is not
enough detail.
env-js/test/specs/console/spec.js:6: module is not a function
in env-js/test/specs/console/spec.js at 6

I take it '..../qunit.js' is a typo?
Where can I get the code to repro?

Ok, attached should be a tar.gz file.
tar -xzvf dumper.tar.gz
gsr -f dumper/consoletest.js
BOOM
it's maybe 10 lines of code total, and it look like it involves gpsee.include.
// This throws an error but no core dump
//module('coredump');
// THIS CORE DUMPS
require('gpsee').include('dumper/spec.js');
spec.js is one line "module('anything');"

I'm having a hard time reproducing your results. First I had to change
GPSEE_PATH so
that dumper/*.js would work with require(). With that change I only got this
output
which tells me I still have more work to do to get to where you are:
JS strict warning #162 in qunit.js at line 396 - reference to undefined property
window.location
JS strict warning #162 in qunit.js at line 493 - reference to undefined property
window.jQuery
JS strict warning #162 in qunit.js at line 310 - reference to undefined property
window.setTimeout
Uncaught exception in dumper/spec.js:2: module is not a function
I'd guess I'm missing env.js, but you don't seem to include it anywhere.
Ohhh... are
you running this in Firefox?

and of course, at work I cannot reproduce it.
When I'm home I will do a wipe and redo and report back. I was very
consistently getting the core dump over the
weekend.
sigh.

Marking Invalid. Suspect something like out-of-sync DSOs.
Please re-open if this re-occurs.
