pydarshan summary: "ValueError: Record nbins is not consistent with current heatmap"

[pramodk]

In the attached folder we have four files:

$ ls -lrt darshan-logs/
total 32
-rwxr-xr-x@ 1 k  staff  2412 Nov  7 01:04 merge.darshan
-rwxr-xr-x@ 1 k  staff  2052 Nov  7 01:04 0_python_id19032-19038_11-7-8-10602490067385980188_1.darshan

0_python* are created from 3 sub-processes and merge.darshan using:

darshan-merge *.darshan --output=merge.darshan

Individual darshan-job-summary on the above 4 files work fine. But if I try to use PyDarshan summary on merged report then we get:

$ python -m darshan summary merge.darshan

ValueError: Record nbins is not consistent with current heatmap.

I have attached the logs here.
