Summary

0000051: standard reconstruction segfaults in GetLastDOCAPoint()

Description

Trying to complete a reconstruction sample on the grid, and getting a recurring segfault in reconstruction. How to reproduce:

1. Grab the file http://zeus.phys.uconn.edu/halld/gridwork/bug-3-21-2011/events_3806.hddm [^] - a single event that causes the segfault.
2. Build the latest version of the reconstruction code (as of 3/18/2011) on either x86_64 or i686 platforms, both show the same feature. I have only tested this with default optimization -O2.
3. Run "hd_ana -PPLUGINS=danahddm -PTHREAD_TIMEOUT=300 events_3806.hddm".
4. Watch it segfault.

Notes
(0000065) davidl (administrator) 2011-03-21 10:40	Was not able to reproduce this problem on OS X, but was on CentOS 5.3 (64bit). Committed fix in svn revision 7603. It was due to use of a NULL pointer for last_swim_step in DReferenceTrajectory::GetLastDOCAPoint. Currently awaiting confirmation of fix from Richard before marking issue as resolved.

(0000067) davidl (administrator) 2011-03-21 14:44	Fix has been confirmed. Marking issue as resolved.
