fudge / gltrail Goto Github PK

glTrail --twitter always crashes about 5 seconds after a twitter message is shown. A few twitter messages are shown before it crashes.

Windows reports:

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

When run under QtCreator, I see the following on the Application Output panel:

Starting C:\Qt\glTrail\src\bin\gltrail.exe...
ASSERT: "!isEmpty()" in file ....\2010.05\qt\include/QtCore/../../src/corelib/tools/qlist.h, line 271
Invalid parameter passed to C runtime function.
Invalid parameter passed to C runtime function.
QWaitCondition: Destroyed while threads are still waiting
C:\Qt\glTrail\src\bin\gltrail.exe exited with code 3

Windows 7 (no SP)
Qt Creator 2.0.1
Qt 4.7.0 (32 bit)

I don't have experience working with QtCreator. I'm still trying to discover which thread crashed and how to get a backtrace.

The most suspicious thread is thread number 2, at qvector.h:

        } QT_CATCH (const std::bad_alloc &) {
            if (aalloc > d->alloc) // ignore the error in case we are just shrinking.
                QT_RETHROW; // << HERE
        }

Any ideas?
