[Qt-interest] help tracking down memory corruption on Mac Qt 4.7.3 Cocoa (64 bit)

[Anton Chernov]

Ok, got it, thank you.

In my case i have often very bad behavior in qt-creator including crashes
and stuff and the thing that helps - store all intermediate files in 1
directory (tmp/moc;tmp/uic;tmp/obj), delete them all if needed (religious,
huh?) and delete THE MAKEFILES. I have read somewhere that qmake uses
qfilesystemwatchers for tracking files and they have a limitation on system
file handlers count (256). On huge projects with hundreds of directories
this could be potentially the cause for skipping rebuilds...
