compile lttng get gcc compile error

[loody]

hi all
when I try to cross-compile lttng-tool for arm.
I get below message

  CC     kernel-consumer.lo
kernel-consumer.c: In function 'lttng_kconsumer_snapshot_channel':
kernel-consumer.c:324:1: internal compiler error: in gen_movsi, at
config/arm/arm.md:5680

my gcc version is 4.7.4

thanks for your help in advance,
