Hi all, I have done some more testing on this. My guess is that something changed on our RedHat Enterprise Linux 6 computers, such that the creator stopped working overnight. It worked on 2/16/2012 just after I installed the SDK package and on 2/17/2012 it would crash with
(gdb) bt #0 0x00007f430af121bd in sqlite3Step () from /opt/qt/qt-4.8/QtCreator/lib/qtcreator/plugins/sqldrivers/libqsqlite.so #1 0x00007f430af0461b in sqlite3_step () from /opt/qt/qt-4.8/QtCreator/lib/qtcreator/plugins/sqldrivers/libqsqlite.so #2 0x00007f430aec680d in QSQLiteResultPrivate::fetchNext(QVector<QVariant>&, int, bool) () from /opt/qt/qt-4.8/QtCreator/lib/qtcreator/plugins/sqldrivers/libqsqlite.so #3 0x00007f430aec741c in QSQLiteResult::exec() () from /opt/qt/qt-4.8/QtCreator/lib/qtcreator/plugins/sqldrivers/libqsqlite.so #4 0x00007f430b6a1139 in QSqlQuery::exec() () from /opt/qt/qt-4.8/QtCreator/lib/qtcreator/plugins/Nokia/../../libQtSql.so.4 This weekend I tried number of things. I was no longer able to install qt with the installer: Qt_SDK_Lin64_offline_v1_2_en.run. It would core dump as soon as the installation process started. Unfortunately, the core dump did not have any useful information, at least nothing that would enlighten me. What is more, I have been using Qt 4.7.0 (installed from SDK), which worked for me for a year or so. When on 2/17/2012 I started the creator program from the 4.7.0 installation, it also no longer works, it crashes with the same back trace in the core dump as the newer one. I am able to build a working version of Qt 4.8 and creator 2.4 from sources on these RedHat PCs. Tuesday, I will engage our local Unix administrators, maybe they can help me understand what happened. I am working at SLAC, which is a National Accelerator Laboratory and all Linux computers are centrally maintained. There is a Taylor program which runs every night on these computers and does upgrades, etc. on these computers.
