crash - kernel debugging utility, allowing gdb like syntax
||Ubuntu 16.04 LTS (Xenial Xerus)
||Ubuntu Updates Main i386
||Ubuntu Developers <email@example.com>
The core analysis suite is a self-contained tool that can be used to
investigate either live systems, or multiple different core dump formats
including kdump, LKCD, netdump and diskdump.
o The tool is loosely based on the SVR4 crash command, but has been
completely integrated with gdb in order to be able to display
formatted kernel data structures, disassemble source code, etc.
o The current set of available commands consist of common kernel core
analysis tools such as a context-specific stack traces, source code
disassembly, kernel variable displays, memory display, dumps of
linked-lists, etc. In addition, any gdb command may be entered,
which in turn will be passed onto the gdb module for execution.
o There are several commands that delve deeper into specific kernel
subsystems, which also serve as templates for kernel developers
to create new commands for analysis of a specific area of interest.
Adding a new command is a simple affair, and a quick recompile
adds it to the command menu.
o The intent is to make the tool independent of Linux version dependencies,
building in recognition of major kernel code changes so as to adapt to
new kernel versions, while maintaining backwards compatibility.

crash (7.2.3-1) unstable; urgency=medium
* Fix for a crash-7.2.2 regression that may cause the "mount" command to
generate a segmentation violation. The bug is dependent upon the compiler
version used to build the crash utility, where a buffer overrun is not
seen with more recent versions of gcc, which hide the bug due to a
different stack layout of a function's local variables.
* Fix for a second crash-7.2.2 buffer overrun regression that may cause the
"rd -S" option to generate a segmentation violation if a displayed memory
location contains a slab object address.
* Fix for a third, highly unlikely, crash-7.2.2 buffer overrun regression,
that could potentially occur during session initialization.
