Research direction
Start by reproducing the crash: a small Objective-C program that casts a dispatch_data_t to NSData and sends -description, which the report says segfaults. Then find where the NSData toll-free bridge for dispatch data is handled in the Base library sources. The payload names no files, so locate them yourself. Done means the cast-and-describe case runs without crashing and returns a description.
Written by the indexing model from the issue text.
Description
Type-casting an dispatch_data_t object to NSData and sending -description results in a segmentation fault. I assume bridging doesn't quite work.
