QDir: Conditional jump or move depends on uninitialised value(s)
Unsolved
General and Desktop
-
Hello,
I've found an error reported by valgrind:
Conditional jump or move depends on uninitialised value(s)To reproduce it:
1- Create a new Qt Widgets Application.
2- Name it and use default option.
3- In mainwindow.cpp:3 add: #include <QDir>
4- In MainWindow constructor add:
QDir dir = QDir("/tmp/");
QStringList filter = QStringList("*.txt");
QFileInfoList fileInfoList = dir.entryInfoList(filter);
5- Set a BreakPoint on these last line.
6- Create an empty /tmp/main.cpp file with: touch /tmp/main.cpp
6- Start application using Valgrind Memory Analyser with GDB.
7- Step Over (F10)
GDB stop in Disassembler (??)
Memcheck reports:
Conditional jump or move depends on uninitialised value(s)
in 0xf3e4ca5
1: 0xf3e4ca5
2: 0x8e4e717Followed by a second one:

Please provide a minimal, compilable example and what Qt version you're using. Are you sure QtWidgets is needed? Also please install the Qt debug sources to see if it really happens inside Qt. I don't see anything with valgrind and Qt5.15.x

Qt Creator 4.14.0
Based on Qt 5.15.2 (GCC 10.2.0, 64 bit)

I get this error in Console Application too:#include <QCoreApplication> #include <QDir> int main(int /*argc*/, char */*argv*/[]) { QDir dir = QDir("/tmp/TestFolder"); QStringList filter = QStringList("*.txt"); QFileInfoList fileInfoList = dir.entryInfoList(filter); return 0; }/usr/bin/valgrind --child-silent-after-fork=yes --xml-socket=127.0.0.1:38587 --log-socket=127.0.0.1:38201 --xml=yes --smc-check=stack --tool=memcheck --gen-suppressions=all --track-origins=yes --show-reachable=yes --leak-check=full --num-callers=25 --vgdb=yes --vgdb-error=0 /home/phenom/build-Test_QDir-Desktop-Debug/Test_QDir

When this is the valgrind output of the unconditional jump then I don't see what Qt can do against it - it's deep inside libpcre2-16.so.0, maybe even in another library called from there.
-
It could be an uninit parameters?
Maybe a better coder than me can report it to libpcre2 maintainers if he can reproduce it?
I never said it's Qt bug. ;)I had install eschwartz/qt5-base-debug 5.15.2-2.1 but Qt creator never show source file.
Hello,
I get ride of using Qt debug source.
When using Qt compiled source (from Maintenance Tool), I get this error too.
But if I use self compiled one(/Qt/5.15.2/Src/configure -developer-build -opensource -nomake examples -nomake tests), nothing happens. It seems that it doesn't use /Qt/5.15.2/Src/qtbase/src/3rdparty/pcre2/src/pcre2_jit_match.c:57 where error occurs.Here the Backtrace just after error (after some F11 to get Call Stack):
