[Qt-interest] QList is crashing when detructed?

[Eric Clark]

Thank you Thiago. Is there a way to force Qt to use my malloc (nedmalloc) without having to rebuild Qt? I have overridden the global new and delete operators. I believe the issue lies in that when Qt uses new internally, it is using malloc and then when I try to delete the object, my app uses nedfree instead of free. Not sure, but this seems to be what is causing the problem.

Thanks,
Eric

Make sure Qt and all Qt's dependencies (including the standard C++
library) are using nedmalloc too.

You can't use an allocator just for one part of the application. It has to be used everywhere.
