[Coin-lpsolver] problem in addRow of OsiClp

[Anureet Saxena]

hi,
   
  I am using the trunk version of OsiClp and valgrind reports a bug on the following code. The valgrind error is attached at the end. No such bug is reported when the same code is compiled and run with the stable version of Osi obtained via the stable version of Cgl; this suggests the problem originates somewhere in the recently modified trunk version of the code.
   
  I will greatly appreciate if someone could help me fix this. 
   
  regards & thanks,
  anureet
   
  PS: I will be more than happy to use the stable version of the code, except that some of the COIN-OR code I am using (cbc bonmin etc) depends on the trunk version of OsiClp.
