Subject: [PATCH] Avoid being smart about keeping only a single reference to
|
|
the buffer.
|
|
|
|
When pdf_dev_pop() is called it will drop the reference to the buffer.
|
|
pdf_dev_push_new_buf() will either create a new buffer reference or take a reference to the existing buffer.
|
|
When pdf_dev_pop() is called unbalance this creates a problem as the
|
|
top level buffer will be unreferenced too many times.
