Description Remi Collet 2017-06-14 07:26:23 EDT

Working on qelectrotech, we encouter segfault on app exit

(gdb) bt
#0  0x00007fdf53d07f73 in QIcon::~QIcon() () at /lib64/libQt5Gui.so.5
#1  0x00007fdf526f13d0 in __run_exit_handlers () at /lib64/libc.so.6
#2  0x00007fdf526f142a in  () at /lib64/libc.so.6
#3  0x00007fdf526d7408 in __libc_start_main () at /lib64/libc.so.6
#4  0x00005559f4cb509a in _start ()

Digging, this seems related to .svg file used in the application

Converting all .svg to .png avoid this segfault (but this look like a workaround)

Could be related to https://github.com/MaartenBaert/ssr/issues/508

Notice: this seems to be Fedora specific issue
(upstream cannot reproduce on Debian with Qt 5.7.1, Windows, MacOS...)


Reproduced on Fedora 25, 26 and RHEL-7

Application: https://qelectrotech.org/download.html
Source RPM: http://rpms.remirepo.net/SRPMS/qelectrotech-0.60~rc2-2.remi.src.rpm
(fedora only have 0.50 for now, which is not affected)
