[Bug libc/779] New: no ptmalloc_init in public_mTRIm

["mwdalton at stanford dot edu" <sourceware-bugzilla at sources dot redhat dot com>]

public_mTRIm()erroneously contains no code for initializing malloc's 
data structures if it is the first malloc-related function called.  A 
simple test wherein malloc_trim() is called before any other memory 
allocation function should verify that this causes a program crash. 
The proper fix would appear to be just adding a simple 
if(__malloc_initialized < 0) ptmalloc_init (); 
at the beginning of public_mTRIm(). I'm not sure if these functions are
supported, but public_iCOMALLOc and public_iCALLOc also have the
same bug. Thanks for your help

Mike
