GCC 3.0 branch segfaults when compiling KDElibs

[Luke Mauldin <lukeskyfly at txk dot net>]

Hello, I compiled qt-2.3.0 with the gcc-3.0 branch(checked out on 6-03-01) 
and it works and compiles fine.  However, there are two problems that gcc 
encounters when trying to build KDElibs-2.1.2.  The first is a problem with 
function calls.  Here is the error message.  make[3]: Entering directory

If I go into the files and change the function calls from simply strcpy(...) 
to std::strcpy(...) it works and compiles fine.  I am not sure if that is a 
bug or if that is kde's fault?  I know that it does compile correctly with 
gcc-2.96 and gcc-2.95.3.  The second error message I get is when gcc 
segfaults.  Here is that error message:

It did create a core file.  I am not sure how to get information from the 
core file though, so if you need information from that, please tell me how to 
get it to you, and I will be more than happy to provide you with all of the 
information possible.
