Crash opening file with absurdly large path
Migrated from https://bugs.launchpad.net/inkscape/+bug/1474359
Steps to reproduce
- Create file
<svg xmlns="http://www.w3.org/2000/svg"><path d="m 0 0 v 1e309 -1e309 0" /></svg>
- Open in Inkscape
Test file from launchpad (d="m 9. 45E+7 -3 -693 -4e-766 .3718e7 4,3425E0681,+98 -3.0e02643 -9. 9")
)
What happened?
Crash
(org.inkscape.Inkscape:3119): glibmm-ERROR **: 03:09:42.835:
unhandled exception (type std::exception) in signal handler:
what: lib2geom exception: Non-contiguous path (../src/3rdparty/2geom/src/2geom/path.cpp:1043)
Backtrace: inkscape-backtrace-crash-large.txt
We also crash if you create a path and replace the d attribute's value in the xml editor. That crashes with the shorter d="m 0 0 v 1e309"
. However, a path with that value won't crash on opening the file.
We still crash in shell (i.e. without GUI).
What should have happened?
No crash.
I guess we're going to end up with #1446
