Using the backwards search (Cmd-f, and then the backwards arrow) in Skim with High Sierra, the program crashes after some hits of the search (a variable number of them, depending on the word). I could not get it to crash in forward search so far.
In attachment, you can find the crash report for one of this instances.
The crash is a duplicate. That already happened in Sierra.
Is there another issue open for this then? I couldn't find it. Just experienced this issue myself after updating to 1.4.30.
Perhaps you mean something different? Backward search has to do with
pdfsync. Is that not what you mean?
This crasher finds place inside PDFKit. This is Apple's bug which only they
can fix.
