--- Comment #1 from Petr Pisar  ---
The t/plplot.t crashes when executing "3D color plot, low level interface" test
when calling plshades() Perl subroutine:

The crash is in plplot library when dereferencing grid variable, debugger
states the pointer is inaccessible:

void
pltr1( PLFLT x, PLFLT y, PLFLT *tx, PLFLT *ty, PLPointer pltr_data )
{
    PLINT   ul, ur, vl, vr;
    PLFLT   du, dv;
    PLFLT   xl, xr, yl, yr;

PLcGrid *grid = (PLcGrid *) pltr_data;
    PLFLT   *xg   = grid->xg;
    PLFLT   *yg   = grid->yg;
    PLINT   nx    = grid->nx;
→   PLINT   ny    = grid->ny;

It does not crash when running under gdb or when executed from vim. Maybe some
kind of a race condition.

This is the minimal reproducer:

use PDL;
use PDL::Config;
use PDL::Graphics::PLplot;

my $dev = 'xfig';

# Test shade plotting (low level interface)
plsdev ($dev);
plsfnam ("test12.$dev");
plspage (0,0, 600,600, 0,0);
plinit();
pladv (0);
plvpor(0.1, 0.9, 0.1, 0.9); 
plwind (-1, 1, -1, 1);
plpsty(0);

my $nx = 35;
my $ny = 46;
my $x = (sequence($nx) - ($nx/2))/($nx/2);
my $y = (sequence($ny) - ($ny/2))/(($ny/2) - 1.0);
my $xv = $x->dummy(1, $y->nelem);
my $yv = $y->dummy(0, $x->nelem);
my $z = -sin(7*$xv) * cos (7*$yv) + $xv**2 - $yv**2;
my $nsteps = 15;
my ($zmin, $zmax) = $z->minmax;
my $clevel = ((sequence($nsteps)*(($zmax - $zmin)/($nsteps-1))) + $zmin);
my $xmap = ((sequence($nx)*(2/($nx-1))) + -1); # map X coords linearly to -1 to
1
my $ymap = ((sequence($ny)*(2/($ny-1))) + -1);
my $grid = plAllocGrid ($xmap, $ymap);
plshades($z, -1, 1, -1, 1,
         $clevel, 2,
         0, 0, 1, 
         0, &pltr1, $grid);

It happens even if I disable GSL support in PDL that is problematic on PowerPC.

I will disable the package on PowerPC. It never worked there and I'm unable to
debug it.

--- Comment #9 from Fedora End Of Life  ---
This message is a reminder that Fedora 26 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 26. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '26'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 26 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

--- Comment #11 from Fedora End Of Life  ---
Fedora 26 changed to end-of-life (EOL) status on 2018-05-29. Fedora 26
is no longer maintained, which means that it will not receive any
further security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
