:I am trying to track down why ktrace shows
:RET select -1 errno 4 Interrupted system call
:
:But errno has 672964768.
:
:The code uses selecterr = errno or
: selecterr = (* __error());
:
:selecterr is an int.
:
:And prints out that selecterr.
:
:Any ideas on where 672964768 is coming from?

Yup. That's &errno instead of errno. I would expect that to occur
if 'errno' is #define'd more then once since sys/errno.h basically
depends on errno not already being defined. When it is multiply
defined the trick sys/errno.h uses breaks down and you wind up with
a mess.
I'll bet something in the program is trying to manually #define errno.
