Hi,
When trying to get GPT working on the current OpenBSD snapshot I ran
into a kernel crash. This is caused because the readgptlabel() passes an
incorrect size to the last free() call in the function.
The size is stored in a variable 'gpsz'. However this variable is
defined twice, in the function scope and in the for scope. This is
obviously incorrect. The patch below fixes this.
Kind regards,
David
