I need some help.

I have rebuild Emacs for debugging (master April 28, cee4128135):

  ./autogen.sh
  ./configure --prefix=/c/LocalApps/Emacs
  [...]
  Configured for 'x86_64-w64-mingw32'.

  Where should the build process find the source code?    .
  What compiler should emacs be built with?               gcc  -g3 -O2 
-gdwarf-2
  [...]

then I have run it from command line in MINGW64 shell

  /c/LocalApps/Emacs/bin/runemacs.exe &

and without initialization files (without ~/.emacs.d/ folder). Indeed in 
this case Aspell is found in the PATH

  echo $PATH
  /mingw64/bin:/usr/local/bin:/usr/bin[...]

Then attached GDB (from mingw-w64-x86_64-gdb 7.12.1-2 package)

  ps -W | grep emac
     6756       0       0       6756  ?              0 22:19:13 
C:\LocalApps\Emacs\bin\emacs.exe

  gdb -p 6756

Continuing.

At this point, in Emacs I visited this file:

  cat test.tex
%%
%%
%%

\caption{5\% \label{_fred}}
\autoref{alice} envolope

%%

and tried to flyspell (M-x flyspell-mode), but Aspell crashed, as 
described and Emacs stopped to respond.

In the window shell all I could capture was

[Thread 6756.0xc3c exited with code 0]

GDB didn't give me a prompt for "bt"...

How to get th backtrace?
