QtCreator leaks a lot of memory on Mac OSX

QtCreator leaks memory very fast when running app with message output to "Application output" window inside of QtCreator. After a while OSX suspends the QtCreator due low memory.

Problem occurs with iOS, Android and OSX native with output to "Application output" but if I redirect OSX native to terminal, there is no leak. The nasty issue is that there is no way to redirect Android or iOS to terminal so I could just run app few minutes.

My application is very verbose but still debug output is in maximum long run in tens or hundred kilobytes, not gigabytes.

This issued has not appeared in previous Qt5.4 versions but least following ones has it:
qt-opensource-mac-x64-ios-5.4.0-rc_2014-11-13_02-57-22-70.dmg
qt-opensource-mac-x64-android-ios-5.4.0-rc_2014-11-17_09-59-42-72.dmg

Exact QtCreator version:
Qt Creator 3.2.82 (3.3.0-rc1-opensource)
Based on Qt 5.4.0 (Clang 6.0 (Apple), 64 bit)
