# this patch is from Mark Hatle <mark.hatle@windriver.com>, who  ran into 
# a random segfault using the latest module-init-tools (3.12) and finally
# trace back to depmod.c:grab_module, which appears that the new malloc(...) 
# setups up things, but never clears the memory that was just allocated.
