wxt hang on 5.0.4 and recent cvs on ubuntu 14.04 amd64

[Tatsuro M. <tma...@ya...>]

I have built gnuplot 5.0.4 or recent 5.1.0 on Ubunutu 14.04 amd64.
The wxt terminals hangs.

(On 5.0.3, wxt terminal works correctly.)

Version 5.0 patchlevel 4    last modified 2016-07-21 


gnuplot> set term wxt
Terminal type set to 'wxt'
Options are '0 enhanced'
gnuplot> pl x
terminated (core dump)

On recent 14.04, I have met the same hang.


Running on gdb,
gnuplot> pl x

If I use this version of gnuplot for octave

>> setenv GNUTERM wxt
>> graphics_toolkit gnuplot
>> plot (1:10)

Fatal Error: Mismatch between the program and library build versions detected.
The library used 2.8 (no debug,Unicode,compiler with C++ ABI 1002,wx containers,compatible with 2.6),
and yo>> ur program used 2.8 (no debug,Unicode,compiler with C++ ABI 1009,wx containers,compatible with 2.6).

Seems to be mismatch of ABI of wx 2.8.

I do not thing that this is a bug of gnuplot. But some new codes of gnuplot trigger the faults on my system.

Any suggestions?
