As a quick work-around, you could try to do the following:

1.) configure the patched gcc 4.2 with "--with-dwarf2 --disable-libssp"
2.) start to compile it with "make all install"
3.) read the error message that is generated. This error message refers to one 
specific line in the file "gcc/gcc/dwarf2out.c" of the gcc sources.
4.) comment out the "assert" statement that generates the problem and that 
checks for stack and arg pointer for stack frame offsets.
5.) again start "make all install"

The stack frame offsets will still be wrong (as they were from the very 
beginning), but at least some part of the debugging should be working.
