[Bug c/44723] New: unrecognizable insn during stage 2 compilation of gcc/coverage.c


On both SLE10 SP3 and SLE11 SP1, trying to bootstrap an unpatched snapshot of
trunk (at 161589) using the system provided binutils, I get

/home/jbeulich/cpp/gcc/trunk-svn/2010-06-30/gcc/coverage.c: In function
?htab_counts_entry_hash?:
/home/jbeulich/cpp/gcc/trunk-svn/2010-06-30/gcc/coverage.c:151:1: error:
unrecognizable insn:
(insn 25 7 26 2 /home/jbeulich/cpp/gcc/trunk-svn/2010-06-30/gcc/coverage.c:150

        (mem/s:SI (plus:DI (reg/v/f:DI 5 di [orig:64 of ] [64])
                (const_int 4 [0x4])) [15 entry_2->ctr+0 S4 A32])) -1 (nil))
/home/jbeulich/cpp/gcc/trunk-svn/2010-06-30/gcc/coverage.c:151:1: internal
compiler error: in extract_insn, at recog.c:2127

Bootstrapping the same snapshot on i686-pc-linux-gnu is going fine.
