#25 X Error of failed request in octave


Plplot 5.5.0
compiled on Suse 9.0
with option: --prefix=/opt

Testing examples in /opt/share/plplot5.5.0/examples/octave
for some of them I get the following error:

X Error of failed request: BadGC (invalid GC parameter)
Major opcode of failed request: 56 (X_ChangeGC)
Resource id in failed request: 0x4f5c
Serial number of failed request: 11319
Current serial number in output stream: 13684

when instructions like the following are called

plmesh(xx', yy', z', opt(k) + MAG_COLOR);

However, instruction like

plmesh(xx', yy', z', opt(k));

do not give problems.
Plplot 5.3.1 does not show the same problems

    Fixed in xwin.c rev 1.126. I haven't tested this case
    specifically, so this
    isn't definitive, but a similar case showing the same
    problem now works fine.
    Please verify & close.

    According to Maurice's comments at the time this should have been fixed. There have been no further reports on this, and I have been unable to reproduce the error with 5.9.5 so I am closing the bug.
