Hi, last two days, we had various report of CVS top version lrn
seg-faults. I v been looking into this.
Chris reported seg-faults related to DSTHeader not initialized. I have not
been able to reproduce this in either my account or blast account
(cvs_v3/BlastLib2_dev.)
Michael and Vitaliy reported seg-faults but did not include and detail. It
would be helpful to send a copy of the screen dump at seg-fault.
I have been able to create a seg-fault in TBLNewDer::fit. However, I am
having a little trouble tracing it.
This seg-fault does not happen when compiled with -g flag. So there goes
the chance to debug it in GDB. I inserted check points. But just to
disgust my stomach, it someties happens in TBLNewDer::fit and sometime
in TBLFitTrack::Sim.
For the moment, try compile BlastLib with -O2 flag:
configure ...... --enable-debug
make clean
make
to see if seg-faults still. I will try to fix this problem as soon as
possible.
