>Description:
Sometime between 20030309 and 20030311 I started getting crashes in g++.other/decl5.C as shown between these two reports:

http://gcc.gnu.org/ml/gcc-testresults/2003-03/msg00575.html
http://gcc.gnu.org/ml/gcc-testresults/2003-03/msg00732.html

gdb says:

>How-To-Repeat:
Target mips-sgi-irix6.5 and compile decl5.ii with:

cc1plus -fpreprocessed decl5.ii -quiet -dumpbase decl5.C -ansi -auxbase-strip /var/tmp/gcc-testing/branch/build/gcc/testsuite/decl5.o -pedantic-errors -Wno-long-long -ansi -version -fmessage-length=0 -o decl5.s
