Summary: I can plot a 3D surface on Windows 7, I used to be able to plot the same on Mageia 4, when I upgraded to Mageia 5 I get "Error: Command crashed: filename-1.asy" and using dmsg I see a segmentation fault.
Please help!!!
Detail:
GENERAL
Thank you for looking at this. :0)
The error I get from TexStudio is "Error: Command crashed: asy -noprc minimal3D-1.asy" (or "Error: Command crashed: asy filename-1.asy" if I don't use -noprc)
dmesg | grep asy
[ 1159.645219] asy[28118]: segfault at 1b150 ip 00007f6a4a0f2f61 sp 00007ffe09692fe0 error 4 in i965_dri.so[7f6a49ff5000+559000]
Please note three things:
1) My asymptote code works perfectly on Windows 7 (the problem is with a Linux implementation only) e.g. see pdf
2) My asymptote code used to work perfectly on Mageia 4; i.e. before I did a clean install of Mageia 5 (I have NOT changed the asymptote code)
3) Asymptote 2D works perfectly on both OSs (the problem just concerns 3D rendering on Mageia 5)
My thoughts:
- I think I am missing a dependency or some setting is wrong somewhere.
- It's not a Mageia 5 problem.
- It's not a TeXstudio problem.
- It's not a a bug in Asymptote
asymptote is started with either:
asy ?m.asy
or
asy -noprc ?m.asy
PDF viewer (and likewise PS, DVI) is set to either:

\begin{equation}
G(s)=\frac{s+1}{s-1}

We plot the function $G(s)$ for all values of $s=\sigma+j\omega$ over the range $(-2.5,-1.5)\le(\sigma, j\omega)\le(2.5,1.5)$. The input' values are plotted in the normal complex plane, theoutput' values are gain (height) and phase (colour.)
There is an inherent ambiguity in how to measure $\pm 180\degree$. It is this that is responsible for the phase discontinuity. We have chosen the interval $-\pi\le\theta\le\pi$ but we could equally have chosen $0\le\theta\le2\pi$ or even $0\ge\theta\ge-2\pi$.

Since it is a 3D rendering, could you precise the version
of Ghostscript (there are some recent changes in asymptote
to support recent version of Ghostscript, but linux distributions
have in general older version).
The error message seems to be related to Direct Rendering,
could you verify that 3D rendering is ok with another software ?
(perhaps glxgears can help).
O.G.

Found the problem: It's a KDE4 / Plasma thing. My code works perfectly under Bodhi Linux (on a very old PC). So it's nothing to do with TeXstudio settings, Asymptote, Ghostscript or anything else. See https://bugs.freedesktop.org/show_bug.cgi?id=86281

1. CONFIG FILE
~/.asy/config.asy is:
import settings;
settings.outformat="pdf";
batchView=false;
interactiveView=true;
batchMask=false;
interactiveMask=true;
gs="/usr/bin/gsc";

also tried other settings including:

INSTALLATION CHECK
TeXstudio 2.9.4 (hg :)
Using Qt Version 4.8.6, compiled with Qt 4.8.6 R
Asymptote 2.32 and xasy both installed.
The known 3D "bug" occurs if the following is missing:
/usr/share/texmf-dist/tex/latex/media9/media9.sty
it is not missing.

Hello
Since it is a 3D rendering, could you precise the version
of Ghostscript (there are some recent changes in asymptote
to support recent version of Ghostscript, but linux distributions
have in general older version).
The error message seems to be related to Direct Rendering,
could you verify that 3D rendering is ok with another software ?
(perhaps glxgears can help).
O.G.
Sorry about the delay and thank you for replying.
- The Ghostscript version is 9.14
- I will try "Blender" to check whether 3D animations can be done
Found the problem: It's a KDE4 / Plasma thing. My code works perfectly under Bodhi Linux (on a very old PC). So it's nothing to do with TeXstudio settings, Asymptote, Ghostscript or anything else. See https://bugs.freedesktop.org/show_bug.cgi?id=86281
