[Darshan-users] Problem with darshan-job-summary.pl in 3.3.0

[Phil Carns]

Hi all,

We followed up in more about this off-list, but just to post here for 
the sake of posterity, the fix is in 
https://github.com/darshan-hpc/darshan/pull/394 and will be available in 
the next Darshan release.

thanks,

-Phil
