create an empty file called t.hh.
create a file called t1.cc with:
#include "t.hh"
extern __inline__ int
stat (__const char *__path, struct stat *__statbuf) throw ()
{
--------------
compile the PCH like:
g++ t.hh
and the source file with:
g++ t1.cc -save-temps --param ggc-min-expand=0 --param ggc-min-heapsize=0 
And see the following ICE:
t1.cc: In function ‘int stat(const char*, stat*)’:
t1.cc:4: error: expected `}' at end of input
t1.cc: At global scope:
t1.cc:4: internal compiler error: Segmentation fault

I should note I found this wil trying to figure out why a libstdc++ testcase
was failing.

------- Comment #3 from pinskia at gcc dot gnu dot org  2006-03-13 02:41 -------
Just a note the reason why this is ICE on valid and not just ICE on invalid is
because the source to t1.cc could also be:
#include "t.hh"
extern __inline__ int
stat (__const char *__path, struct stat *__statbuf) throw ()
{
}
-----
And it still ICEs.

I am almost wanting to say this was caused by the openmp merge but I don't know
for sure.

This worked with "4.2.0 20060306" so it has to be a recent change.

------- Comment #6 from pinskia at gcc dot gnu dot org  2006-03-13 22:34 -------
This is a blocker as I reduced it from a failing libstdc++ testcase.

CCing the developers of the openmp patch since that is the only patch to the
C++ front-end which could have caused this within the dates I gave.

GCC 3.4.4 seems to compile the testcase fine though (sorry about the linker
error, nobody specified -c on the build command line):

#include "t.hh"
void foo() {}
