Please, look at the bottom of page
http://gcc.gnu.org/onlinedocs/gcc-3.3.3/gcc/Extended-Asm.html#Extended%20Asm :

i386 floating point asm operands

There are several rules on the usage of stack-like regs in asm_operands insns.
These rules apply only to the operands that are stack-like regs...

According to these rules, your asm should be written as:

  asm ("fmulp": "=t" (ret): "0" (ret), "u" (tmp): "st(1)");

Uhm.  It's very hard to not crash on randomly broken inline-asm.

------- Comment #4 from reichelt at gcc dot gnu dot org  2009-09-20 20:42 -------
The code is invalid. But the compiler shouldn't crash on invalid code.
So this is an ice-on-invalid-code bug.

So, invalid.
