257328 - Program terminated with signal SIGTRAP

Status: RESOLVED EXPIRED

(SeaMonkey :: General, defect)

Description

[Harald Dunkel]

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.8a3) Gecko/20040829
Build Identifier: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.8a3) Gecko/20040829

If I try to run Mozilla under control of gdb, then I get

Program terminated with signal SIGTRAP, Trace/breakpoint trap.
The program no longer exists.
(gdb) 


Reproducible: Always
Steps to Reproduce:
1.build the current Mozilla snapshot using "configure
--prefix=/usr/local/stow/mozilla-1.8 --enable-default-toolkit=gtk2
--enable-crypto --enable-debug"
2.run "mozilla -g" and enter "run" at GDB's prompt




Platform: Debian for amd64, based upon gcc-3.4.1. 

Seems that gdb 6.1 and 6.2 can't debug pthread applications on amd64 at all. But
the current snapshot for GDB is much better. Actually, this might be a problem
of GDB, but Google shows that the error message "Program terminated with signal
SIGTRAP" came up before, and it was always related with Mozilla or Firefox.

This problem seriously affects debugging, so I would suggest to increase its
priority.

PS: I could attach gdb to a running Mozilla, so I guess its not _that_ important
anymore.

"current Mozilla snapshot", does that mean you used the Debian source for
building Mozilla? If yes, please use
http://ftp.mozilla.org/pub/mozilla.org/mozilla/nightly/latest/mozilla-source.tar.bz2
 or
http://ftp.mozilla.org/pub/mozilla.org/mozilla/nightly/latest/mozilla-source.tar.gz
to build Mozilla (the Debian People modified Mozilla source).

No, I have not used the Debian version. Latest snapshot means
http://ftp.mozilla.org/pub/mozilla.org/mozilla/nightly/latest-trunk/mozilla-source.tar.bz2
Please check the provided Build Identifier.

I know that the Mozilla folks don't care very much about amd64, even though it
is getting more and more important. Can you reproduce the problem?

[Dan Mosedale (:dmosedale, :dmose)]

I don't have an amd64 machine to reproduce, though shaver might.  My suspicion
is that this is a gdb bug, since I can't find any instances in the Mozilla code
proper to SIGTRAP.  It's conceivable that one of the libraries (eg GTK) is
causing it, I suppose.

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

I do at least half of my development on an amd64 (fedora core 3) system with
FC3-stock gdb and gcc and kernel, and I haven't had that problem.

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.
