Alex Crichton 2f3c412c84 std: Disable usage of mmap allocator in libbacktrace This is sort of a long overdue change from the investigation in #29293 and #37477. The released binaries of rustc don't have debug information and so don't actively suffer this problem but this can hit local development of rustc and also larger programs compiled against libstd generating backtraces. The main purpose of the mmap allocator in libacktrace is to be usable from a signal handler, but we don't do that, so the normal allocator using malloc/free should work well for us.		2017-10-25 07:51:36 -07:00

README

The libbacktrace library
Initially written by Ian Lance Taylor <iant@google.com>

The libbacktrace library may be linked into a program or library and
used to produce symbolic backtraces.  Sample uses would be to print a
detailed backtrace when an error occurs or to gather detailed
profiling information.

The libbacktrace library is provided under a BSD license.  See the
source files for the exact license text.

The public functions are declared and documented in the header file
backtrace.h, which should be #include'd by a user of the library.

Building libbacktrace will generate a file backtrace-supported.h,
which a user of the library may use to determine whether backtraces
will work.  See the source file backtrace-supported.h.in for the
macros that it defines.

As of September 2012, libbacktrace only supports ELF executables with
DWARF debugging information.  The library is written to make it
straightforward to add support for other object file and debugging
formats.
