###!!! ASSERTION: URI mapped to two different specs?: 'uriMapEntry->mDocMapEntry
== nsnull', file i:/build/mozilla/xpcom/io/nsFastLoadFile.cpp, line 418
Break: at file i:/build/mozilla/xpcom/io/nsFastLoadFile.cpp, line 418

I've been having fun, so this is definitely a personal bug for the time being.
what i've done:
start with modern, skins switch to classic, load/unload composer, skin switch to
new classic, install german, locale switch to german, ctrl-shift-n (new composer
window). <this assertion here>

My guess is that i really need to address what to do when a locale switches. I
could makke a new fastload file for the locale or change the mapping to include
locales with urls as part of the index. brendan/ben: this is an architecture
question, what do you want me to do? pointers welcome.

I'll try to post a live switching patch to the switching bug before i leave for
thanksgiving.

    NS_ASSERTION(index < aTable->entryCount, "bad nsObjectMap index!");
    vector[index] = entry->mInfo;
doesn't seem to handle the assertion case at all, so i'll have to do something
about that too. if you want me to split those asserts into a new bug, I can.

Comment 2

[Henrik Gemal]

I see this in my debug builds too with latest source. I dont do any locale
switching.
I happens after the last mozilla sessions crashes and I start mozilla again. I
get past the profile manager and then I crash. It's pretty consistent.
the line number has changed from 418 to 422

anything I can do?

can you in anyway check your fastload file? like dump it? test it?

Comment 3

[John Morrison]

Attachment: perl to pick apart fastload file

I think you may be morphing this bug a bit (iirc that assertion could be hit in
some other (rare, I think) cases, but ignoring it (in those cases) was benign).


Anyways, here is my craptastic script for dumping out the contents of a
fastload file. [I really should check this in someday].

Comment 4

[Henrik Gemal]

the only problem I found when starting a mozilla with fastload file that produced:
ASSERTION: URI mapped to two different specs?
was this:

maybe a bad XUL_FASTLOAD_FILE_VERSION? at c:\mozilla\moztools\bin\dumpfastload.p
l line 99.
XUL_FASTLOAD_FILE_VERSION = feedbee7

Comment 5

[Henrik Gemal]

seems like the warning was just due to not having the correct fastload version:
my $XUL_FASTLOAD_FILE_VERSION = 0xfeedbeef - 8;
6 changed to 8 and no warnings

I just hit this with a debug build that I clobbered last night...
