Jeff, I tried mainline too now.

With tree-ssa I get (after setting ulimit -v 400000, or it crashes my box :-)

steven@steven:~/devel/ssabuild/gcc> ./cc1plus -isystem ./include -quiet t.cc
t.cc: In function `int main()':
t.cc:24: warning: cannot pass objects of non-POD type `struct A' through 
`...'; call will abort at runtime
t.cc: In function `void PrintArgs(Type, ...) [with Type = A]':

Segmentation fault


With mainline it fails more gracefully with

t.cc: In function `int main()':
t.cc:24: warning: cannot pass objects of non-POD type `struct A' through 
`...'; call will abort at runtime
t.cc: In function `void PrintArgs(Type, ...) [with Type = A]':
t.cc:24:   instantiated from here
t.cc:15: warning: cannot pass objects of non-POD type `struct A' through 
`...'; call will abort at runtime
t.cc:17: warning: cannot receive objects of non-POD type `struct A' through 
`...'
virtual memory exhausted: Cannot allocate memory

So this is not tree-ssa specific.
