--- Comment #2 from Ian Lance Taylor <ian at airs dot com> ---
I committed a patch so that libbacktrace should no longer segfault when no
memory is available.
If other compilers can print a backtrace when mmap fails, then I think they
must be recording all necessary information in loadable sections. When no
memory is available we could print a trace of PC addresses, but it would be
very painful to print file/line information. We could stage the I/O through a
static buffer, but finding the information to print without being able to build
any data structures would be very inefficient.
