memory leak from valgrind on ex1

[Umut Tabak]

Dear all,

I was trying to locate my memory-leaking problems due to a class I wrote 
in combination with Petsc, during these checks I used valgrind in the 
very basic modes, but there is a point I could not understand about 
Petsc programs. I used the example which is the in the "getting started" 
section of the manual(${PETSC_DIR}/src/ksp/ksp/examples/tutorials/ex1.c).

A linear system solution. Using valgrind on this problem reported some 
"definitely lost" parts. I could not understand this error. Can someone 
help me on understanding this point, I am not a pro, but want to become 
a user of Petsc by trying to understand the main parts of the library?

I used  "valgrind --leak-check=yes ./ex1"

Best regards,
Umut
