[Bug c/36782] New: php-5.2.5, error: unable to find a register to spill in class 'R0_REGS'

["masaki dot chikama at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

gcc-4.3.0 fail to compile php-5.2.5 with this message.
gcc-4.1.3 can compile without failure.

It's similar to Bug #36684, But -fno-schedule-insns option doesn't help.
I can comiple when I down optimization level (remove -O2).
Is this simply -fno-schedule-insns is ignored by other option ?
