[Bug c/18753] New: GCC internal error with -O3 and -finstrument-functions with gcc-3.4

["vdanjean at free dot fr" <gcc-bugzilla@gcc.gnu.org>]

The internal error can be triggered with the following code :

static inline void foo(void) { }
void bar(void) { foo(); }

with the command line :
gcc -O3 -finstrument-functions -c test.c

I obtain :
test.c: In function `foo':
test.c:2: internal compiler error: in cgraph_expand_function, at cgraphunit.c:540
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
For Debian GNU/Linux specific bug reporting instructions,
see <URL:file:///usr/share/doc/gcc-3.4/README.Bugs>.

I do not have the bug with -O2 instead -O3, nor without  -finstrument-functions,
nor with gcc 3.3

I tried the following compilers :
