ABR for new in purify C++

[vijkrr]

Code :

vector<char> ab; //Assume it may or may not have data.

size = ab.size();
char* ch = NULL;
if ( size > 0 )
{
ch = new ch(size); // Purify is throwing ABR for this line.
}

Can anyone help what could be the issue?

Same kind of allocation is present twice. For 1st its not showing the error and for second its showing error.

ch = new ch(size); // Purify is throwing ABR for this line.
I expect you meant
ch = new char[size];

yes its ch = new char[size];
