 No, it is not fixed on the 3.3 branch:
 pr9373.cpp: In member function `void Thread::hook_ipc_vector()':
 pr9373.cpp:11: internal compiler error: in set_mem_alias_set, at emit-rtl.c:
    1932
 Please submit a full bug report,
 with preprocessed source if appropriate.
 See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
 
 gcc version 3.3 20030205 (prerelease)
 
 You need to have checking enabled in your build to get it.

 The reduced testcase looks legal to me.
 The compiler seems to have trouble to identify "Mword" and "unsigned".
 If I only use one of those inside the struct, everything compiles fine.
