User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; de; rv:126.96.36.199) Gecko/20080331 Firefox/188.8.131.52 Build Identifier: Mozilla Thunderbird Version 184.108.40.206 (20080331) Hi, I noticed that my Thunderbird (x86_64) does not display many attachments (i.e. all pdf attachments) properly when compiled with gcc-4.3. When the mail arrives the paperclip icon is being displayed in the list. After I click onto the the mail to get it displayed in the preview area the paperclip disapears and no attachment is being shown. The problem also exists for old mails. The attachment afterwards is still existent on the mail server (I use IMAP). Using mozilla-thunderbird-bin-220.127.116.11 (binary version from gentoo) everything can be displayed properly. I already tried to create a new profile and to recompile thunderbird with minimal CFLAGS and LDFLAGS, but the problem was still there. I recently recompiled my system (gentoo) with gcc 4.3, thus as a last step I recompiled with gcc-4.2.3 and everything works as ususal. Reproducible: Always Steps to Reproduce: 1.build thunderbird with gcc-4.3 2.try to read mails with attachment
I can confirm this bug with Thunderbird 18.104.22.168 compiled with gcc-4.3.0 on x86_64.
Have you tested building cvs HEAD?
I can confirm this too, gcc 4.3.0, thunderbird 22.214.171.124, x86_64, but with pop accounts. I haven't tested HEAD (don't have time for that right now - maybe I'll try in the weekend)
The problem is still present in the new version of Thunderbird: 126.96.36.199. I can confirm that both POP and IMAPs accounts have this bug.
Can confirm that the problem persists in 188.8.131.52.
Confirming based on the comments of multiple people. Can someone try HEAD too?
Not an issue anymore here: after removing almost all patches we have applied on archlinux, this issue wasn't fixed yet. After unsetting CFLAGS and CXXFLAGS and removing the --enable-optimize=$CFLAGS thing from .mozconfig, thunderbird works reliable and no longer has problems with attachments when compiled with gcc 4.3.
Hit the same problem with Thunderbird 184.108.40.206 and 220.127.116.11 x86_64/linux and gcc 4.3.0.
Gentoo users confirm this issue as well, along with the hack of --disable-optimize fixing the issue. http://bugs.gentoo.org/show_bug.cgi?id=223375
Works for me with gcc-4.3.1
