Details:

Dear octave maintainers,

I built octave-4.2.0 from source on cygwin32 and I get a panic while trying to
read a file 

I run octave directly from the build dir as a test:

$ ./run-octave
[ ... ]
octave:1> A = rand(2,4) ;
octave:2> dlmwrite('A.txt',A,';') ;
octave:3> dlmread('A.txt',';') ;
panic: Segmentation fault -- stopping myself...
attempting to save variables to 'octave-workspace'...

The file "A.txt" seems ok:

$ cat A.txt
0.1306441452814343;0.8857767385559925;0.9683188499526589;0.7098461239802842
0.7245152910945072;0.173438417637011;0.7121772944616351;0.2547977878928745

My configure options are:

./configure --enable-shared --disable-64 --disable-docs \
  --disable-java --enable-threads=windows --enable-bounds-check

Am I doing anything wrong here? Is this a cygwin issue?

Regards,
Julien
