Package:python-pyqt5
Version: 5.11.3+dfsg-1+b3_arm64
Severity: serious
Hi Experts,
Hope this email finds you well.
I am Peng Zongli, I'm sorry to bother you.
When ever I run the example code on the arm machine,It results in the
error below:
/ Could not initialize GLX/
/ Aborted (core dumped)/
but when I run the same example code on the x86 machine(Debian 8.3.0-6),
there is no error.
Debian Release: (gcc version 9.2.1 20191102 (Debian 9.2.1-17))
Architecture: arm (64)
Kernel: Linux 4.19.34-2-arm64
python vesion 2.7.16
python-pyqt5-dbg (5.11.3+dfsg-1+b3)
python-pyqt5.qtwebengine-dbg (5.11.3+dfsg-1+b3)
Qt5 vesion 5.11.3
GLX version: 1.4
Sip vesion 4.19.14
the example code:
/ from PyQt5.QtWidgets import QApplication/
/ from PyQt5.QtCore import QT_VERSION_STR/
/ from PyQt5.Qt import PYQT_VERSION_STR/
/ from sip import SIP_VERSION_STR/
//
/ if __name__=='__main__':/
/ import sys/
/app=QApplication(sys.argv) /
/ print("Qt5 Version Number is: {0}".format(QT_VERSION_STR))/
/ print("PyQt5 Version is: {}".format(PYQT_VERSION_STR))/
/ print("Sip Version is: {}".format(SIP_VERSION_STR)) /
//
/ sys.exit(app.exec_())/
it gives a Python traceback and crash:

And when I uninstall
python-pyqt5.qtwebengine-dbg(5.11.3.1-1+rebuild),the error disappears.
Comparing the gdb log and only found the parameters of
PyRun_FileExFlags: global and locals is missing a part:
'app': <QApplication at remote 0xfffff2a89c30>.
On x86 machines, this part is there.
I don't know if this is the cause of this problem in the end, and I
don't understand why there is such a difference between arm and x86.
I enclose X86 gdb log for your reference.
So far i havent't found any solution how to solve this issue. Could you
help to investigate on this issue, thanks in advance!
Best regards,
Zongli Peng

That patch is now merged and released to Debian in libc6 2.31-1.
So I am closing this bug.
