Ohhkaay... A dot(member access) instead of a comma in a default argument function messes me up! ..C++ void func(tagger* t1, tagger* t2 = NULL) I passed a call func(ttt,tag) instead of func(ttt.tag) which should have been ttt->tag QtCreator converts . and -> appropriately... so I get lazy to using -> at times... Well, it compiled an kept giving me seg faults!! till I almost threw the library away... only to discover my mistake weeks later with a debugger (stack tracing)... |

System trashing I wrote a small numerical program of large 2D double array with a high amount of iterations and had memory leaking at each iteration till it used up 80% of my 2GB RAM! I was surprised Windows didn't complain, it was instead paging other processes!!! |

I also recall, I once wanted to demonstrate a small text editor I wrote following a QtSDK example.... to my friends. I failed to compile it! I couldn't figure it out and they laughed... then the following day, it compiled! thats how I learned about ENVIRONMENT variables and profiles |
