gnuplot caca terminal work on Cygwin-x86 but not Cygwin-x86_64

[Tatsuro MATSUOKA <tmacchant2 at yahoo dot co dot jp>]

Hello 

I have tried to build the recent cvs snapshot of gnuplot both on Cygwin-x86 and Cygwin-x86_64.

The caca terminal works correctly on the Cygwin-x86. However it does not work on  Cygwin-x86_64.

First I have reported in the bug-ticket on the SourceForge of gnuplot. 
https://sourceforge.net/p/gnuplot/bugs/1391/

But I feel that this is not the gnuplot issue but Cygwin-x86_64 issue. Because the caca terminal works fine on  Cygwin-x86

I have tried to execute gnuplot(cvs) on gdb.

gnuplot> set term caca
Terminal type set to 'caca'
Options are 'enhanced size 80, 25 background rgb "white" color noinverted charset blocks'
gnuplot> plot sin(x)

Program received signal SIGSEGV, Segmentation fault.
0x0000000077868e5d in ntdll!RtlUnwindEx ()
   from /cygdrive/c/Windows/system32/ntdll.dll
(gdb) 

The Segmentation fault is occured.
What can I do the further purchase of this issue?

Regards

Tatsuro
