More details, as I admit I was terse
Running secondary is tricky due to the need to map the memory
region at the right place, which is whatever primary has chosen. If
the base address for primary happens to by already mapped in the
secondary, we will hit precisely this error message (well, in a few
case we might hit the other one). This is why there is already
a comment about ASLR.
A colleague of mine hit that message and was misled by errno
claiming "permission denied", which sent him down the wrong
track. It's such a common error for secondary that I feel this error
message should be unambiguous and helpful.
