The libjava testsuite gets a FAIL in the gij PR12350 test. I traced this to a
SIGBUS in a yet to be determined location in verify.cc. When verify.cc is
compiled with -O0 the test PASSes.
This is with the svn trunk -r118192. I am fairly certain that the same problem
exists in the 4.2 branch as I am getting the same FAILures there, but have not
investigated in detail.
I know this is kind of vague. I will try to get a proper reduced testcase
soon. Unfortunately the failure mode is such that it is impossible to get a
backtrace at the point of the SIGBUS. The PC is getting set to a point in
unmapped memory evidently after doing a 'jr v1' which is kind of a wierd thing
to be doing.
