df4e529 mistakenly switched
PayloadHeader::data
from using a non-standards compliant (but accepted by most compilers) flexible array to a pointer. This resulted in an attempt to dereference the uninitialized contents of the array.This patch eliminates
PayloadHeader::data
and instead makesFTPRequest::data()
use pointer arithmetic to get the data buffer from within the payload buffer.This fixes the crash, but the plugin still doesn't work quite right, at least with ArduPilot. The only command I have been able to execute successfully is checksum.
Fixes #1695
