MALLOC_CHECK_=2 in distcheck?

[Karl Berry]

I wonder about setting the envvar MALLOC_CHECK_ to 2 in the standard
distcheck target generated by automake?  Of course it will have no
effect on many systems, but it could catch memory errors on GNU/Linux
systems.

I don't think there's any way to accomplish this with a hook, since it
has to be set at the crucial point where the main command gets run:
        dc_install_base=`$(am__cd) $(distdir)/_inst && pwd | sed -e 
's,^[^:\\/]:[\\/],/,'` \
        ...

Just a thought.

Thanks,
