Hi all!
Last time I experienced several problems with gnuplot. It is very
important for me, because I generate with the gnuplot a lot of charts for
my PhD thesis.
I've reported it as a bug to the gnuplot team, but now I remind, that
similar problem (SIGSEGV after writing of 12288 bytes to the output
PostScript file) occured in Scilab 2.3 with Debian. Maybe this is
something Debian specific, so I've decided to forward it to this list too.
I would be very gratefull if someone test the attached data and answer me
if the problem occures in other hamm systems too.
If someone knows the solution, please let me know.

Subject: Problems with "pslatex" terminal in gnuplot beta347 (pre3.6) in Debian Linux 2.0 (hamm)
Hello gnuplot developers!
I need to include some complicated plots generated by gnuplot into my
Latex document. However, when I try to use the "pslatex" terminal with
"auxfile" option, the gnuplot fails with SIGSEGV, after 12288 bytes of the
auxiliary PS file is written. I've stated, that this effect depends on the
length (?) and the contents (?!) of filenames (so probably there is
something wrong with memory management). Therefore I attach the
tgz file with sample gnuplot data, which cause the error. The "build" file
invokes the gnuplot with the appropriate parameters. The processing of
phd_w4_s3_l10_wzneur.nsts.gnuplot file causes the SIGSEGV, and the
processing of this_works.gnuplot file (which is just the symlink to the
phd_w4_s3_l10_wzneur.nsts.gnuplot) gives the correct results.
This the output of the gdb's "bt" command after the failure:

PS1. Please answer to address wzab@ipebio15.ipe.pw.edu.pl
PS2. When I try to use "pslatex" terminal without the "auxfile" option, I
get the Latex error message, because it does not understand the
\special{" command (although there are no problems with the
\special{! command). What is the reason of it?
