[Gnuplot-bugs] Gnuplot 4.0 Win32 crashes on plot from file

[Uwe Z. <uw...@kt...>]

Gnuplot 3.8i and 4.0 both crash while plotting a data file using a
format specifier on a data file. The data file has 21 comma separated
columns where every third column is a text formated date (which I
ignore):

#101(Time stamp),101(Seconds),101(C),102(Time stamp),102(Seconds),102(C),103(Time stamp),103(Seconds),103(C),104(Time stamp),104(Seconds),104(C),105(Time stamp),105(Seconds),105(C),106(Time stamp),106(Seconds),106(C),107(Time stamp),107(Seconds),107(C)

a minimum sample which still works:
------------------------
reset
set nologscale y

set xrange [-20:20]
set autoscale y

plot          \
     '030910alogg.csv' \
        every 1:::0::0 \
        using ($1<4700? $1/60.0-60.0:1/0):($2) '"%*[^"]",%lf,%lf,"%*[^"]",%lf,%lf,"%*[^"]",%lf,%lf'\
        axes x1y1 \
        title 'center temp.' \
        with lines linewidth 4 \
    ;
------------------------

but adding another column to the format specifier crashes Gnuplot on
Win32 (WinXP sp1+updates):


------------------------
reset
set nologscale y

set xrange [-20:20]
set autoscale y

plot          \
     '030910alogg.csv' \
        every 1:::0::0 \
        using ($1<4700? $1/60.0-60.0:1/0):($2) '"%*[^"]",%lf,%lf,"%*[^"]",%lf,%lf,"%*[^"]",%lf,%lf,"%*[^"]",%lf,%lf'\
        axes x1y1 \
        title 'center temp.' \
        with lines linewidth 4 \
    ;
------------------------

...independently on which pair of columns I select to read.

Earlier I was able to plot this same datafile with GnuPlot 3.7x where
the column separator could be redefined to be a comma instead of a
whitespace...

Any ideas?
