hi folkz im trying for a new project for first time Qt 4.7 (was used to 3.x) and i thought in using smart pointers but whatever i try i get this

#0 0x00007ffff66c865d in QString:perator=(QString const&) () from /usr/lib/libQtCore.so.4
#1 0x00007ffff7bd9631 in RDCI::RDebug::append (this=0x7fffffffe000, value=..., varname=..., linenumber=@0x7fffffffe060, filename=...,
sourcelocation=...) at rdcitypes.cpp:28
#2 0x0000000000401324 in main (argc=1, argv=0x7fffffffe178) at ../rdcitest/main.cpp:11


here is my source code as an attachmentrdci.tar.gz

in the main.cpp i tried several form from normal pointers to smart pointers and qstring break always there, probably is something stupid but i just don't see it

my os info
kubuntu natty 11.04
kde 4.6.4
qt 4.7.2 latest update
kernel 3.0.0 rc-6 preemp and no preemt just in case

thx in advance for any help
