executable files of gnuplot generated from current cvs source trees are unstable

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

Hello

I have built windows binaries (bu mingw gcc-4.3.0-dw2-TDM), cygwin and djgpp.
The exe files are unstable for all platforms.

I have build windows and cygwin binaries with -g option and traced by gdb.

For windows binaries, when I tried all.dem, gnuplot.exe and wgnuplot.exe crashed at electron.dem.
However under the gdb, all.dem went well but waring og HEAP like at the end of this mail.

For cygwin binary, gnuplot crashed at the prob.dem like at the end of this mail.

Perhaps recent added codes crashes memories somewhere.

Regards

Tatsuro
