[Qt-creator] Slow restart of application while debugging

[Kuiper, Luuk]

I'm working on a rather big application. I build that application in
debug mode. The size of the executable is about 325 MB.
When starting the application for debugging, it takes minutes to
startup.
I can imagine that a lot of processing takes places while and after
reading the symbol table and to initialize the debugger.
But it takes much (and I mean realy much) more time to start up than
when I use plain gdb (10 to 20 seconds).
 
But my biggest problem is, that when I stop running the application, and
I want the start it again, without code changes in between, it takes
that same amount of time again.
When using DDD with gdb, it takes some time to startup, and almost no
time to restart the application, because the symbol table is not
reloaded every time, only after rebuilding the applcation. I don't no if
that is happening in QtCreator, but it looks to me, that some caching
can take place.
 
It takes so much time, that I cannot use the debugger of QtCreator, and
I regret that.
