48236 - crash when attempting to load two non-existent files

Status: VERIFIED DUPLICATE of bug 47927

(Core Graveyard :: RDF, defect, P3)

Description

[Lyle Seaman]

latest nightly build.  Unpack and invoke mozilla with shell script, or directly.
 From pull-down menus, select "Debug" then "Viewer Demos" then "#3 Basic
tables".  This fails because the file does not exist.  So far, so good.  Now
choose Debug->Viewer Demos->#4 Simple tables.  Mozilla crashes -- either SIGILL
or SIGSEGV.  No core is generated.  ??!?!  No core?  agh.

Here's some more gory details:

this worksforme with 080909 mozilla build.  Reporter, what build did you test?

Happens if I attempt to load any file that doesn't exist, twice in a row.  RH
6.1.  Files that do exist are fine, naturally.

asa, are you running as root?

Can't reproduce on Linux 2000-08-10-08.

Comment 4

[WD]

I can reproduce this every time on my Redhat 6.1 system

[Blake Ross]

Adding crash keyword to all open crash bugs that don't already have it...

also in

Does not occur when running as root.  Asa, Jeffrey, are you running as root?

Hm  No symbols.  Got a version of librdf and/or libdirectory that have symbols?

The bug this has been duped against has been fixed, and I'm not seeing this
behavior anymore on Linux build 2000110406. Verified dupe.
