FYI I'm seeing a strange error that starts with libhdf5 messages of which the relevant portion seems to be

...
  #010: ../../../src/H5FDint.c line 207 in H5FD_read(): addr overflow, addr = 140424345352640, size=512, eoa=1905739
    major: Invalid arguments to routine
    minor: Address overflowed
ERROR: LoadError: Error dereferencing object
Stacktrace:

It turns out this can be circumvented by replacing

BaseBenchmarks.loadall!()

with

BaseBenchmarks.load!("linalg")
BaseBenchmarks.loadall!()

Filing this without understanding what is actually going wrong, in case someone else encounters this.
