[laurent at guerby dot net]

------- Comment #2 from laurent at guerby dot net  2009-01-02 12:02 -------
Confirmed on 4.3.2-1 Debian gnueabi

guerby@gcc50:~$ g++ -c -O1 pr36415.c 
pr36415.c:29: warning: inline function ‘const UChar*
icu_3_4::UnicodeString::getBuffer() constÂ’ used but never defined
pr36415.c: In member function ‘virtual UBool icu_3_4::RegexMatcher::find()’:
pr36415.c:128: error: unrecognizable insn:
(insn 70 41 42 3 pr36415.c:122 (set (reg:SI 0 r0)
        (plus:SI (reg:SI 3 r3 [156])
            (mult:SI (reg/v:SI 1 r1 [orig:138 opValue ] [138])
                (const_int 32 [0x20])))) -1 (nil))
pr36415.c:128: internal compiler error: in extract_insn, at recog.c:1990

But this compiles fine at -O0/1/2/3 on trunk rev 142808
