try this:

Code:

struct PDFV_POS pos;
[m_view vGetPos:&pos:x:y];
if(pos.pageno>=0)
{
PDFVPage *vpage = [m_view vGetPage:pos.pageno];
PDFPage *page = [vpage GetPage];
PDF_RECT rect;
rect.bottom = 300;
rect.left = x;
rect.right = y;
rect.top = 100;
if( page != NULL )
{
CGImageRef ref = [image CGImage];
PDFMatrix *mat = [vpage CreateInvertMatrix:self.contentOffset.x * m_scale :self.contentOffset.y * m_scale];
[mat TransformRect : &rect ];
BOOL result = [page addAnnotBitmap: ref :YES :&rect];
Matrix_destroy(mat.handle);
[m_view vRenderSync:pos.pageno];
[m_doc save];
[self refresh];
}
}

No, it doesn't work. It's the same before, the first insert is ok but the others crashes the app.

Page object obtained from PDFVPage are not persist object.
you shall always get Page object from PDFVPage every time.
Page object obtained from PDFVPage will freed after vRender invoked.

Well, I do understand this but, the point is a crash in accessing m_cache status after I had a bitmap annotation.
It seems that the problem is connected with this line of code:

Matrix_destroy(mat.handle);

Commenting it out, we have no immediate crash with EXC_BAD_ACCESS, but I guess this could cause memory problems later?
