I can confirm that applying just this patch, rebuilding cc1plus and
rerunning the libstdc++-v3 testsuite fixes many testsuite failures on
mips-sgi-irix6.5:

/vol/gnu/src/gcc/gcc-dist/libstdc++-v3/testsuite/20_util/auto_ptr.cc: In function `int test07()':
/vol/gnu/src/gcc/gcc-dist/libstdc++-v3/testsuite/20_util/auto_ptr.cc:246: internal compiler error: Segmentation fault

Testsuite results are back to normal now:

                === libstdc++-v3 Summary ===
 
-# of expected passes           1462
-# of unexpected failures       266
+# of expected passes           1946
+# of unexpected failures       10
 # of unsupported tests         7
