The portions you omitted (frames 8 to 13) did include Emacs symbols,
such as `obtain' and `r_alloc_sbrk'.

I believe that the higher levels don't have debug info because this
crash was caused by a call to malloc from the Cygwin DLL that came
from something not directly related to Emacs.  Perhaps some error
message that the Cygwin DLL wanted to pop.  But that's a wild
unsubstantiated guess, no more.
