Details |
Loading the testcase *in a debug build* results in a really tall div and a printf message like
nsLineLayout: ComboboxControl(select)(1)@0x25a06a8 didn't set whad 0,330,-559038737,-559038737!
I don't know whether the memory involved is ever initialized (e.g. to zero) in non-debug builds, so I'm marking this as security-sensitive for now.

bz says that because the nsHTMLReflowMetrics constructor initializes these things (even in non-debug builds), we're never using a value from uninitialized memory. So this bug isn't a security issue.

Is this still an issue? I'd bet the reflow branch fixed this (in particular, I don't see the warning and wouldn't expect anything weird in that testcase).

WFM. Debug rendering is reasonable now (and matches opt rendering), and the warning is gone.
--> Fixed by reflow branch landing (bug 300030).
