18172 - nsCategoryManager.js:27 TypeError: Components.interfaces has no properties

Status: VERIFIED FIXED

(Core :: XPConnect, defect, P3)

Description

[matt beauregard]

apprunner segfaults at some stage after autoregistration is complete, first time
after compile gives error about nsCategoryManager then segfaults, times after
that segfaults only.

version is latest CVS version of Seamonkey, not sure how to find out what
version number that actually is.

Comment 1

[leger]

Sending over the build gurus.

Comment 2

[Jon Granrose]

this isn't a build config issue, looks more like a javascript or xpcom
registration issue.  changing component to javascript and sending to default
component owner.

fwiw, the best way to say what build you're running is to look at the build id
in Help|About which should be something like 1999111908 if you built it right
now.  Or you can just say the timestamp of when you pulled the tree from CVS
which would be the most accurate.

Comment 3

[Mike McCabe]

Passing this on to XPConnect (sorry, John!)

Comment 4

[John Bandhauer]

This is likely independent of the category manager stuff. This looks to me like
a 'nix xptcall problem. Shaver owns those.

Comment 5

[Mike Shaver (:shaver -- probably not reading bugmail closely)]

Are you still seeing this?  This looks a fair bit like the problem we had when
our xptcall assembly was broken.

What compiler are you using?

Comment 6

[Mike Shaver (:shaver -- probably not reading bugmail closely)]

Still want to find out what compiler you're using...

Comment 7

[matt beauregard]

the last one I tried with was gcc 2.8.1. 2.7.something gave the same results.

Comment 8

[lcremeans]

Just wanted to let people know that I've gotten the same crash in exactly the
same place with a SeaMonkeyAll CVS pull from tonight, using gcc 2.7.2.3 on
FreeBSD 3.3-RELEASE, and also on an older version (from a few weeks ago) using
egcs-1.1.2.

Comment 9

[lcremeans]

Ok, updated my system to FreeBSD 3.4-STABLE, pulled the latest lizard, and
rebuilt it using gcc 2.95.2 -- all widgets are visible now, and works as well as
the binaries posted on the site. It still segfaults in the exact same place with
gcc 2.7.2.3, so I wager that it's the older compiler causing the problem.

Comment 10

[Mike Shaver (:shaver -- probably not reading bugmail closely)]

I'm going to get all ambitious and close this, then.  Thanks for the detective
work!
