Crash when manipulating vector hande out of range

[Jan Bol]

Inkscape completely crashes when manipulating vector/node handles.

With out of range I mean: I suspect the error is caused when I move handle in such a way that the resulting curve exceeds a certain canvas size or goes to infinity.

See attached screen print. I always see these red marked curved line bits when it happens.

I went wild with editing handles, but I can't replicate it. But it happens quite often. Almost every time I do some extensive node manipulation.

Inkscape version: Inkscape 0.92.1 unknown
OS Ubuntu 16.04 64 bits

Thanks for the report!

This sounds a lot like bug #1691406.
Could you please confirm if it is in fact a duplicate?

[Jan Bol (jan-bol)]

YW!

It sounds a lot like bug #1691406 indeed, but:

I can not replicate it as mentioned. Also I can not grab anything beyond the reach of the node. Within the reach of the node I can grab. Moving the cursor results in rotating the handle. I can do that 180 degrees, even very close to the node, but the program remains stable.

So yes, it looks similar at the least, but I can not confirm it is the same.

Also the problem occurs in my case without extreme zoom.

could you attach the svg file that caused the original crash?

[Jan Bol (jan-bol)]

Attached the subject file. As I saved over it again it is not in the similar condition when it crashed.

I was tracing text from layer one. The most upper occurrence of "terra"

thanks, crash confirmed on Windows 10, Inkscape 0.92.2pre0 (973e216, 2017-07-25)

DOS crash message is:
terminate called after throwing an instance of 'Geom::ContinuityError'
  what(): lib2geom exception: Non-contiguous path (../src/2geom/path.cpp:1043)

trigger the crash by grabbing using the node tool at a location slightly outside a sharp join.
appears to be a duplicate of Bug #1691406
