1463047 - Crash on startup for self-built Thunderbird

Status: RESOLVED WORKSFORME

(Thunderbird :: General, defect)

Description

[Ben Bucksch (:BenB)]

Environment:
* Ubuntu 16.04 with updates
* Updated gcc from launchpad
  $ gcc --version
  gcc (Ubuntu 6.4.0-17ubuntu1~16.04) 6.4.0 20180424

Code:
* Latest mozilla-central
* Latest comm-central for Thunderbird, in a subdirectory. But the failure is in compiling Mozilla, and Mozilla source is at the top level, so should be irrelevant.
* I did a clobber, and the error persists.
* Same problem with TB 60.

Actual result:
Crash on startup.

Both with a fresh profile and an existing profile:

$ ./mach run
 0:00.18 .../dist/bin/thunderbird -no-remote -profile .../tmp/profile-default
Gtk-Message: Failed to load module "topmenu-gtk-module"

$ ../opt/dist/bin/thunderbird -no-remote -P test
Gtk-Message: Failed to load module "topmenu-gtk-module"
Speicherzugriffsfehler (Speicherabzug geschrieben)
[memory access error, core dumped]

Expected result:
TB starts

Possible causes:
Could be a compiler problem?

Importance:
Blocks me from working on bug 1419417. => Blocker, by definition

Maybe Aceman can help. What is the Gcc you use, Aceman?

Ubuntu 16 seems ancient, but gcc 6.4 should be supported by m-c. I think we even use gcc 4.9 on the servers yet.
I'm using 7.3.


Can you try https://ubuntu-mate.community/t/gtk-message-failed-to-load-module-topmenu-gtk-module/4964 ?

If it doesn't help, can you 'strace ../opt/dist/bin/thunderbird -no-remote -P test' to see if it doesn't stop on something else?

You may also try 
mach artifact toolchain --from-build toolchain-linux64-gcc-6
which should download a mozilla supplied gcc6 into the m-c folder. Then you can try using that compiler just for building TB.
You set these in your .mozconfig:
export CC=.../TB-tree/mozilla/gcc/bin/gcc
export CXX=.../TB-tree/mozilla/gcc/bin/g++

Yes.
