Confirmed.
Reduced testcase (compile with -O -ffast-math):
======================================================
double floor(double);
inline int bar(double x) { return (int)floor(x); }
int foo(int i) { return bar(i); }
======================================================
bug.c: In function 'foo':
bug.c:3: internal compiler error: in get_callee_fndecl, at tree.c:5809
Please submit a full bug report, [etc.]
Happens with C and C++ frontend.
There seems to be something wrong with -ffast-math and floor.
Renaming floor to something else in the above testcase makes things
work again.
