Because this increases the size of malloc appreciably (due to strings
etc), you should say N unless you need to debug a malloc problem.

+ help
+ Answer Y here to compile support for application self-debugging, by adding
+ a new shared object "libubacktrace.so" that provides the following new
+ functions:
+ backtrace, backtrace_symbols, backtrace_symbols_fd
+
+ The backtrace functionality is currently supported on SH platform, and it
+ based on dwarf2 informations to properly work, so any application that
+ want to use backtrace needs to be built with -fexceptions flag.
+
+ The symbol names may be unavailable without the use of special linker
+ options. For systems using the GNU linker, it is necessary to use the
+ -rdynamic linker option too. Note that names of "static" functions are not
+ exposed, and won't be available in the backtrace.
