glibc and seg fault error

aab1990 (26)
I keep running into problems with my program to evaluate baseball stats. When I try to INPUT filename I run into glibc and if run TEAM identifier then i get a segmentation fault. The glibc didn't start happening until I put in the PLayerData.clear() statement.


Thanks in advance

I don't see anything out of the ordinary here. Post your code for Player.
