I don't use gcc-4.2 anymore, but I've never seen such problems with it
on GNU/Linux while using it.

How did you determine that gcc-4.2 is the problem?

Did you try different versions of gcc on the same machine, keeping the
same version of binutils, and only gcc-4.2 had problems?

Have you tried compiling with -O0 ?  Did you also have problems when using -O0 ?
