PulkoMandy 0822ec27a9 libicon: Fix dangling references to VertexSource in PathTransformer
PathTransformer keeps a reference to the VertexSource used (which can be
either another PathTransformer, or the base path for a shape). When a
shape is cloned, this should be retargetted to the new object in the
clone.

However, references are not settable, and so, what would happen instead
is the original (non-cloned) vertex source was reinitialized (through
the default implementation of the assignment operator) using data from
the clone, and the clone would still point to it. Then, if the original
object is deleted, the clone would point to freed memory.

To avoid this problem, replace the reference with a pointer (which can
be set to point elsewhere, as the code intended to do). To make sure
this does not happen again, make the VertexSource copy constructor and
assignment operator private, and deleted when the compiler supports
that.

Fixes #18577

Haiku

Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs

Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.

Goals

  • Sensible defaults with minimal configuration required.
  • Clean, clear, concise code.
  • Unified desktop environment.

Trying Haiku

Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.

Compiling Haiku

See ReadMe.Compiling.

Contributing

Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
