this it's not an hardware problem but related to software (fb embedded), there's same invalid pointer into one of the fb embedded dlls so i want know how retrieve same info to help to debug the problem.
from microsoft docs:
"An access violation occurs in unmanaged or unsafe code when the code attempts to read or write to memory that has not been allocated, or to which it does not have access. This usually occurs because a pointer has a bad value. Not all reads or writes through bad pointers lead to access violations, so an access violation usually indicates that several reads or writes have occurred through bad pointers, and that memory might be corrupted"
