[Halld-offline] problems with reading recent data with many threads

Hi Offliners,

I've run into some crashes reading some of the raw data files taken last
night.  I've been analyzing run 21943 with the latest sim-recon, and have
noticed this problem with files hd_rawdata_021943_001.evio and
hd_rawdata_021943_002.evio

Strangely the crashes seem to occur when I run with many (>20) threads.  I
tried recreating the problem in single threaded mode, but it did not
occur.  I haven't done a scan to see at which point the problem happens,
but it does some to consistently occur at larger thread count.  A snippet
containing the error is below.  Has anyone else seen anything like this?

Cheers,
Sean
