Version:           3.3.4 (using KDE 3.5.4, Debian Package 4:3.5.4-3 (testing/unstable))
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.17-2-686

We have a medium size Makefile project with maybe 100 source files using mainly c++. Also compiles in and links againsty a few libraries (mainly libz, Qt, fftw, blitz).
ABout 1/3rd of the times I run make (explicitly or implicitly through pressing "run") it will either freeze or just not take any more user input. In the latter case the mouse cursor still updates and the text cursor, f.e., still blinks, but there is no effect clicking ort hitting a key.
Maybe should mention that I installed debian from a floppy and then from the net and keep on missing dependencies which I have to pull in manually using apt-get, maybe somethings still missing?
Otherwise: great app. Suggestion: make debian packages with debugging symbols as I also get a few crashes but can't really tell you much without a stacktrace.
