------- Comment #14 from sebastian dot huber at embedded-brains dot de 2010-05-17 09:04 ------- This bug is present since r130052 which is related to:
http://gcc.gnu.org/ml/gcc-patches/2007-10/msg01814.html If this is a generic bug or not is quite irrelevant since this is a very serious bug on ARM/Thumb. I am a bit irritated why this bug survived the 4.4.0 and 4.5.0 release. In a multi threaded environment it is pretty hard to find these kind of problems. The time frame in which an interrupt can corrupt the stack frame lies between two instructions. Is -fno-schedule-insns2 a workaround for this problem? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38644
