i've  stumbled  over  it  just  now.  sh  traps in free() -- someone's
corrupting the heap :(

it's  100% reproducible, and it's traps with 1.1.6 too.

i'm rebuilding cygwin1.dll with MALLOC_DEBUG now. Hopefully, we'll see
who's corrupting the heap.

btw,  how  big  is  MALLOC_DEBUG's  penalty  on performace? perhaps we
should  enable  this  if  configured  with  --enable-debugging? or add
--enable-malloc-debugging?
