achja, sehr seltsam ist die riesen Zahl: Invalid allocation size: 4294967268 bytes (entspricht über 4000gb!) Die erzeugte .exe selber hat nur 250kb.

"Verdächtige" Allokationen testen und/oder mit dem Debugger rantasten.

Hab die exe (beide Versionen, die im Debugordner und die im Release ordner )jetzt mal mit Purify von Rational versucht zu analysieren. Hab leider nicht viel Ahnung von dem Tool - scheint aber ganz hilfreich zu sein. Hab nur Probleme die Ergebnisse zu analysieren:

übrigends stürzt das Programm ab
Was auch noch seeehr seltsam ist - erstelle ich eine kleine "hallo-welt" konsolenanwendung, dann liefert Purify folgendes:

[I] Starting Purify'd test2.exe at 22.11.2003 14:29:46
[I] Starting main

liegt das jetzt am Compiler & XP?

ich honk hab vergessen, die nötigen files mit in den Release bzw Debug ordner zu kopieren - die Pfadangaben im Programm waren nämlich relativ. Also der Absturz ist behoben.
Dennoch hagelt es FMM Fehler - leider zeigt das Tool nicht die Zeile im Code an, die daran schuld ist - oder geht das vielleicht doch??
