             Bug #: 52341
           Summary: crypto/rand FAILs before Solaris 11
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: go
        AssignedTo: ian@airs.com
        ReportedBy: ro@gcc.gnu.org
              Host: *-*-solaris2.{8,9,10}
            Target: *-*-solaris2.{8,9,10}
             Build: *-*-solaris2.{8,9,10}


Before Solaris 11, the libgo crypto/rand test FAILs like this:

--- FAIL: rand.TestRead (0.00 seconds)
    ???:1: Read(buf) = 1040, %!s(<nil>)
FAIL
FAIL: crypto/rand

There's a limit on /dev/urandom here, while not properly documented in
random(7D), it can be found in the OpenSolaris sources and is alluded to in
Solaris 11 random(7D):

     The limitation per read for /dev/random is 1040  bytes.  The
     limit for /dev/urandom is (128 * 1040).

The 1040 byte limit also applies to /dev/urandom before Solaris 11.
