std::vector resize crash

[Daniel J Watkins]

Hi,

When I attempt to resize a column in a 2d vector I receive the error listed
below. I'm using the libraries supplied with VxWorks.

0xf3fe450 (tExcTask): memPartFree: invalid block 0xf340ef0 in partition
0x311b8c

Here is the example code I'm using to produce the error. Any idea's what is
wrong with the code?

#include <vector>

using namespace std;
using std::vector;

void main(void)
{
std::vector< std::vector<int> > triangle(5);

for(int i = 0; i < triangle.size(); i++)
{
triangle[i].resize(i+1);
}
}

Thanks in advance,

Daniel.

}

Everything else is fine.

I have no idea about this VxWorks thing. But if you think it detects an
error, maybe you are using an outdated compiler that uses a buggy
implementation of std::vector. The fact that it accepts void main ( void )
may hint in that direction, too.
