An answer would be much appreciated after the five initial days of this being
ignored as a private mail followed by a further six days of silence out here
in the open on this very list we once set up for help with packaging issues.

Can we ignore valgrind reports which show 'definitely lost: 0 bytes' ?

Curious,  Dirk

|     ==3533933== LEAK SUMMARY:
|     ==3533933==    definitely lost: 0 bytes in 0 blocks
|     ==3533933==    indirectly lost: 0 bytes in 0 blocks
|     ==3533933==      possibly lost: 0 bytes in 0 blocks

| Extensions_ manual notes) to compiler optimisation. So we currently consider
| this spurious.
| 
| Could CRAN let us know if this is considered a 'must fix' issue?  And if so,
| maybe so not show the alarmingly red 'valgrind' link to a report with zero leaks?
| 
| Many thanks as always for all these thorough tests.
| 
| Sincerely,  Dirk
