1003352 - thunderbird 24.5.0 does not build with gcc 4.9.0

Status: RESOLVED WONTFIX

(Thunderbird :: Build Config, defect)

Description

[felix-mozilla]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:29.0) Gecko/20100101 Firefox/29.0 (Beta/Release)
Build ID: 20140429162646

Steps to reproduce:

I tried to compile thunderbird using gcc 4.9.0.  In comm-esr24/mozilla/mfbt/tests, compiling TestAtomics.cpp fails.

Note that I am using stock gcc 4.9.0 compiled from the sources, no distro patches either to gcc or glibc or any other piece of software involved.


Actual results:

Expected results:

I have never even seen this error message.  It appears to be new with gcc 4.9.0.
When I remove TestAtomics.cpp from CPP_UNIT_TEST in the Makefile, the build continues.  It's not done yet but it has not thrown this bug anywhere else so far.

Note that I compiled Firefox 29 with the same gcc today, too, and it did not have this error and compiled OK. It also appears to work OK.

Related in any way to bug 1002002 which is a crash in xpcshell code ?

TB 24 is no longer supported.
