the register values coming back from sigreturn(2). Normally this wouldn't matter because the 32 bit environment would truncate the upper 32 bits and re-save the truncated values at the next trap. However, if we got a fast second signal and it was pending while we were returning from sigreturn(2) in the signal trampoline, we'd never have had a chance to truncate the bogus values in 32 bit mode, and the new sendsig would get an EFAULT when trying to write to the bogus user stack address. |
