            Bug ID: 102030
           Summary: private memory overflow in openCL
           Product: Mesa
           Version: 17.2
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Mesa core
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: janpieter.sollie at dommel.be

Created attachment 133229
  --> https://bugs.freedesktop.org/attachment.cgi?id=133229&action=edit
program source

the program is attached, I debugged using the following:
-gdb break 380 & print answer
-investigation of answer[7] and answer[8]
while in both moments of the program they point to exactly the same array, the
content is different.  The only thing that happened in between is the
SHA1Init(&ctx), which should not interfere with output[] and k_pad/digest.
