Crash on drawing to canvas

Hi TLCers,
I experienced a strange problem with in Tk's canvas.
I'm working on a dxf viewing program and am drawing many lines, circles,
e.g.
.mf.frame.pw.f0.frame.sw.c create line 347.007250 -247.562322 \
302.794127 -247.562322 -fill #ff0000 \
-dash {2 2 3 2 2 2 2 2 2 2 3 2 2 2 2 2 2 2 1 2} -tags *

... and after many such commands I get the error:

X Error of failed request: BadValue (integer parameter out of range for
operation)
Major opcode of failed request: 55 (X_CreateGC)
Value in failed request: 0x1a000b2
Serial number of failed request: 1204
Current serial number in output stream: 1205

There is no fixed location where it crashes and there seems to be some
timing depending behavior.
If I put a delay before the drawing command, it crashes on other
locations and sometime it does not crash.

Code part:
puts $b
after 10
{*}$b
puts ok

When removing the delay, it crashes very soon.
It also seems to depend on using the -dash option, because when I remove
this option the program does not crash (at least in my tries - also
without the delay).

Any ideas where to check?
Any hints for analyzing the problematic point?
Where to place a bug report (if it is one)?

When you say "after many such commands I get the error...", approximately how much geometry are you talking about? I will say that I can't reproduce the error under these circumstances:

- ActiveTcl 8.5.9
- Win7, 64bit
- 250,000 line entities using your mentioned attributes (including the -dash property)

Sorry, no Linux available at the moment.

It's a complaint out of the X11 layer that something's gone wrong
(dashes work in a very different way on Windows and OSX/Aqua, so they
can't be compared). Haven't had the time to examine the problem yet, but
I'm guessing that it is a problem with the dash processing as that's
less frequently used than many other parts of Tk's rendering layer.

I can confirm this.
I have tested now:
tcl8.4 - this version works rock solid
tcl8.5 - crashes always
tcl8.6 - crashes frequently or later (after more draw commands)

Nothing found on Windows until now, tested tcl8.5 and tcl8.6 on XP and
Win7 (not all combinations).

Where/How can I submit a bug report?
What information does it need?

The dxf file has ca. 55Kb, the script a few KB but it iuses several
packages.
