Summary REGRESSION: Crash occurs when reloading PDF file
Chris Petersen
Reported 2006-05-02 08:22:01 PDT
This crash only occurs when reloading a PDF file with TOT Webkit. This is a recent regression since the wasn't occuring with the r14124 NB. I can reproduce this 100% with the r14154 NB. Steps to reproduce: 1) With TOT Webkit, go to http://www.uscis.gov/graphics/formsfee/forms/files/i-9.pdf 2) After PDF loads, reload the page 3) Crash occurs

Moving this to the text component since that is where the backtrace is.

Although this is probably some memory management issue, I'm pretty astonished by the backtrace. We're clearing our font caches just because we loaded a PDF file? That seems crazy (and makes me worry we're observing the wrong notification).

Created attachment 8088 [details] Patch that fixes some problems (but still crash further along) This fixes 2 crashes. There's a third crash even after fixing these two though.

This issue is fixed but there is a remaining crash triggered by PDF viewing. http://bugzilla.opendarwin.org/show_bug.cgi?id=8893
