bad_alloc when allocating array

Question

I have this code on the constructor of a class:

verts=new GLfloat[nVerts];

verts is a member variable of the class (GLfloat *) and nVerts is 4. Is something wrong with that code? I get the same error If i try to do malloc(sizeof(GLfloat)*nVerts) I think I'm not running out of memory, because If i change that line of code to another part of the code(for example to the method that calls the constructor just before calling it, like this: GLfloat *test=new GLfloat[4] it works)

Answer 1

I'd check 3 things:

1. Are you 100% sure that nVerts is 4?
2. Isn't memory really exhausted?
3. Isn't your heap corrupted? valgrind can help you with that.
