Boost::lexical_cast error when usin Qtcreator with MSVC2010 compiler, but no error when using VisualStudio for the same code

Hi,
I'm right now porting an console app i wrote using VS2010exp into Qt creator (widget based project).
I use boost::lexical_cast extensively in the code. In Vs it compiles and runs fine. The same code in Qt results in an error (without indicating a special line of code):
@

I have no clue what could cause this. Has anyone a hint for me? Thanks

Which compiler are you using in Qt Creator? The microsoft or the mingw one?

[Phileas Fogg]

The Microsoft one...
And it's Boost 1_47 I use.
