Access Violation in std::pair
- by sameer karjatkar
I have an application which is trying to populate a pair. Out of nowhere the application crashes.
The Windbg analysis on the crash dump suggests:
PRIMARY_PROBLEM_CLASS: INVALID_POINTER_READ
DEFAULT_BUCKET_ID: INVALID_POINTER_READ
STACK_TEXT:
0389f1dc EPFilter32!std::vector<std::pair<unsigned int,unsigned int>,std::allocator<std::pair<unsigned int,unsigned int> > >::size+0xc
INVALID_POINTER_READ_c0000005_Test.DLL!std::vector_std::pair_unsigned_int,
unsigned_int_,std::allocator_std::pair_unsigned_int,unsigned_int_____::size
Following is the code snap in the code where it fails:
for (unsigned i1 = 0; i1 < size1; ++i1)
{
for (unsigned i2 = 0; i2 < size2; ++i2)
{
const branch_info& b1 = en1.m_branches[i1]; //Exception here :crash
const branch_info& b2 = en2.m_branches[i2];
}
}
where branch_info is std::pair<unsigned int,unsigned int>
and the en1.m_branches[i1] fetches me a pair value.
