Description Andrei Slavoiu 2020-11-11 12:34:59 UTC
Tested with USE=-lto and it works fine, but with USE=+lto I get:

Comment 2 Sam James archtester gentoo-dev Security 2020-11-11 18:58:28 UTC
Dying when passing things into Qt is weird:

I suggest you report this upstream because it's unlikely to be related to how we package Wireshark in Gentoo.

Did you use any command like arguments?
Comment 3 Arusekk 2020-11-25 07:29:16 UTC
Confirmed. Any invocation of wireshark that instantiates QCoreApplication is crashing (e.g. wireshark crashes, but wireshark --help does not).

Crash happens because wireshark somehow defines QCoreApplication::self (a static member) multiple times:
gdb -nx -ex 'b /usr/src/debug/dev-qt/qtcore-5.15.1-r1/qtbase-everywhere-src-5.15.1/src/corelib/kernel/qcoreapplication.cpp:773' -ex r wireshark
(gdb) p &QCoreApplication::self
$1 = (QCoreApplication **) 0x555555cc8020 <QCoreApplication::self>
(gdb) disassemble /s $rip,+8
Dump of assembler code from 0x7fffefda9b73 to 0x7fffefda9b7b:
772         Q_ASSERT_X(!QCoreApplication::self, "QCoreApplication", "there should be only one application object");
773         QCoreApplication::self = q;
=> 0x00007fffefda9b73 <_ZN23QCoreApplicationPrivate4initEv+51>: lea    0x2b7b2e(%rip),%rax        # 0x7ffff00616a8
   0x00007fffefda9b7a <_ZN23QCoreApplicationPrivate4initEv+58>: mov    %rbx,(%rax)
End of assembler dump.

So later on QCoreApplication::instance() 's this is a null pointer, resulting in the crash.
Comment 4 David Korth 2020-12-04 01:40:57 UTC
I'm seeing the exact same crash with =app-admin/keepassxc-2.6.2. (with qt-5.15.2)

Stacktrace is effectively the same as the posted trace from wireshark.

Disabling LTO on both fixes both.
Comment 5 Andrew Udvare 2020-12-24 03:33:58 UTC
I am getting the same crash with Wireshark 3.4.2.
Comment 6 Sam James archtester gentoo-dev Security 2020-12-24 21:12:39 UTC
(In reply to Andrew Udvare from comment #5)
> I am getting the same crash with Wireshark 3.4.2.

Please report the issue and link it here as I can’t reproduce it right now.
Comment 7 jannis 2020-12-25 22:09:06 UTC
Thank you so much for pointing out that it works with USE="-lto". I was desperate why wireshark works on my desktop machine but won't start on my laptop!
Comment 8 Arusekk 2021-01-07 16:54:06 UTC
As per the keepassxc comment, the real problem might be that dev-qt/qtcore is not prepared to handle its library variables being replaced by the executable. Because they are.

This is reproduced if the final executable (wireshark/keepassxc) uses all of -flto and -fPIE linker flags, because replacing -fPIE with -fPIC uses the exported symbol from the library.

So maybe qtcore -flto is linked with -fPIE instead of -fPIC too? (while being a library, so this would be very wrong)
Comment 9 Gary E. Miller 2021-01-30 23:11:55 UTC
I can confirm this builds a working wireshark on gentoo unstable:

USE=-lto emerge =net-analyzer/wireshark-3.4.3

Thanks for the tip.

Can confirm this, too.
And that I get a crash in doActivate() with USE=lto.
