Hmm interesting. Using this little change to your app I could "fix" the problem in \
kdevelop:

--- report_old/bug149240.cpp    2007-08-27 12:05:07.000000000 +0200

     {
         if(m_buf)
             free(m_buf);
-        m_size = (len+17) & ~0xF;
+        m_size = (len+1)*sizeof(char);
         m_buf = (char*)malloc(m_size);
         m_len = len;
         memcpy(m_buf, s, m_len);
 @ -33,7 +33,7  @

     string(dword size = 0)
     {
-        m_size = (size + 16) & ~0xF;
+        m_size = size*sizeof(char);
         m_len = 0;
         m_buf = (char*)malloc(m_size);
         m_buf[0] = 0;

And the full GDB output gives a hint that GDB doesn't report a change for m_size and \
m_buf variables when stepping over the assignment in line 67. So this looks like a \
gdb-mi bug (I'm using gdb 6.6 here) not a kdevelop problem. This can also be seen in \
the variables view, only the watch (which is always evaluated) and the m_len member \
are highlighted "red" indicating they have changed.
