Hi,
Since the inclusion of sparcv9a-mont.s/.pl, I get a SIGBUS error when
running bntest. Package is openssl 1.0.0 with sparcv9a on Linux 2.6.34
with a sparcv9 environment (64-bit kernel, 32-bit userspace/v8/v8plus)
on a sun4v US T1 CPU. I am aware of the FPU implications - openssl just
chooses sparcv9a by default, so I stumbled across this.
Any insight would be appreciated.
Program received signal SIGBUS, Bus error.
