[Bug target/19750] New: [3.4] RTL checking failure in gcc.dg/titype-1.c

[ghazi at gcc dot gnu dot org]

With today's 3.4.x CVS, when configured with --enable-
checking=misc,tree,rtl,rtlflag,gc --enable-languages=c,objc,c++,f77,java --
enable-multilib=no I get an RTL checking failure on x86_64-unknown-linux-gnu in 
gcc.dg/titype-1.c:

gcc.dg/titype-1.c:21: internal compiler error: RTL check: expected elt 0 
type 'E' or 'V', have 'i' (rtx reg) in ix86_va_arg, at config/i386/i386.c:3331

To reproduce, run this command:
cc1 -fpreprocessed titype-1.i -quiet -dumpbase titype-1.c -mtune=k8 -ansi -
auxbase titype-1 -pedantic-errors -ansi -version -o titype-1.s

I think this still can happen on the mainline even though the code has been moved to the tree level, we 
still access container the same.
