582424 - TM: JSRopeNodeIterator warning

Status: RESOLVED FIXED

(Core :: JavaScript Engine, defect)

Description

[Gregor Wagner [:gwagner]]

Whenever I use the JSRopeNodeIterator I get a warning like:
..... warning: ‘iter.JSRopeNodeIterator::mUsedFlags’ may be used uninitialized in this function
..... note: ‘iter.JSRopeNodeIterator::mUsedFlags’ was declared here

Sorry about that. I'm not getting the same warning on my machine, so it must be configuration-specific.

Your fix works. You can also remove the "mUsedFlags = 0;" line in JSRopeNodeIterator::init and change it to "JS_ASSERT(mUsedFlags == 0);".

It only happens in the --enable-optimized shell.
