Some demos cannot work correct cvs source (2010-05-08)

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

Hello

I have checked out the cvs source and build it on cygwin and MinGW.
On cygwin, demo freezes at prob.dem.
On MinGW

1. surface1.dem
Hit return to continue (24)

splot [-2:1][-1.5:1.5] mand({0,0},compl(x,y),30)
                                                     ^
"surface1.dem", line 214: All points z value undefined

2.prob.dem
ymax = 1.1 * laplace(mu, mu, b) #Mode of laplace PDF used
       ^
"prob.dem", line 471: undefined value

The above did not occur by the cvs source at 2010-05-06.

However,
2010-05-08  Hans-Bernhard Broeker  <br...@ph...>

	* src/eval.c (magnitude): Make implementation robust to overflows
	and underflows.

the above change seems to not cause the directly cause the bug.

I do not figure out what is wrong at present.


Regards

Tatsuro
