Darshan version 3.4.2 is now officially available for download here: https://www.mcs.anl.gov/research/projects/darshan/download/. This point release includes important bug fixes for Darshan's new PnetCDF module:
* Fixed segfault when defining scalar variables in PnetCDF module
* Fixed bug attributing all PnetCDF variable instrumentation to the first variable instrumented
* Fixed memory corruption (and potential segfault) when reading/writing high-dimensional PnetCDF variables using vara/vars/varm interfaces
* Fixed crashes related to using PnetCDF vard interfaces with input MPI_DATATYPE_NULL datatypes
Note that these bugs can only be triggered by the PnetCDF module released in Darshan version 3.4.1, which is disabled by default. There should be no impact on Darshan 3.4.1 configurations that did not explicitly enable PnetCDF instrumentation.
We have also released PyDarshan 220.127.116.11 on PyPI, though this is just to track the 3.4.2 darshan-util library. There are no new modifications to PyDarshan functionality.
Documentation for Darshan and PyDarshan is available here: https://www.mcs.anl.gov/research/projects/darshan/documentation/.
