That variable doesn't do anything on OSX, so congratulations that xalloc
works on OSX, but you haven't done stringent memory checking yet. Try
{{{
export DYLD_INSERT_LIBRARIES=/usr/lib/libgmalloc.dylib
}}}
instead. see `man libgmalloc` for various options to select what should be
guarded.
(warning: It will run MUCH slower and take MUCH more memory. It seems
gmalloc is about as strict as `ElectricFence` which is also incredibly
slow. Valgrind is speedy by comparison)
