[Trilinos-Users] epetra map constructor gives error

[Heroux, Michael A]

Antonella,

I suggest running this through valgrind or another memory checking tool.
Also, you might consider compiling with ³-g -O0² to keep symbols and
prohibit optimization.  All of these things together should give you a
good idea of where the memory error is occurring.
