 Neither of the reduced test cases causes any segfault on powerpc-linux for me
with gcc 4.0.

I can reproduce this with 3.4.0 and I get the following backtrace:
#0  0x0083b41e in _int_free () from /lib/tls/libc.so.6
#1  0x0083c72b in free () from /lib/tls/libc.so.6
#2  0x0808a3b2 in _cpp_pop_buffer (pfile=0x8b45960) at ../../gcc/cpplib.c:1960

#7  0x08053b2d in c_lex_with_flags (value=0x8408b14, cpp_flags=0x0) at 
../../gcc/c-lex.c:308
#8  0x08054087 in c_lex (value=0x2c622c61) at ../../gcc/c-lex.c:436


But with an slightly old 4.0.0 (two months old, 20041124), I cannot reproduce 
this with either of the 
reduced testcases.
