How can I redirect glibc's dump output to a file -- it seems to ignore
redirection
of stdout and stderr.
Barring that, how can I disable the output -- i.e. just let it leave
the coredump?
Thanks
In case This wasn't clear, I mean output like the below.
Maybe good enough would be redirection or elimination of the
memory map, which seems to be uniquely useless.
Even the stack backtrace echoed to the screen is useless for
most purposes -- no one is willing or able to work from such useless output
so why is it dumped to the screen anyway?
