Trying to visit the following sites causes Safari 4.0.3 and Webkit Version 4.0.3 (6531.9, r50235) to crash. http://ksturnpike.com/ http://sam.nipl.net/brace/ I marked this one as major because, while it doesn't happen on every site when this bug occurs there is nothing to indicate what happened.
FWIW, I cannot reproduce this Please attach crash logs for both sites <http://webkit.org/quality/crashlogs.html>. If the root causes for the crashes are different, we'll really need separate bug reports for each.
When Safari/Webkit crashes, the crash log dialog never comes up. The following messages appeared in the console under Webkit. http://ksturnpike.com 11/9/09 8:53:31 AM [0x0-0x399399].org.webkit.nightly.WebKit[23693] Error occurred during initialization of VM 11/9/09 8:53:31 AM [0x0-0x399399].org.webkit.nightly.WebKit[23693] Incompatible minimum and maximum heap sizes specified 11/9/09 8:53:31 AM com.apple.launchd.peruser.501[171] ([0x0-0x399399].org.webkit.nightly.WebKit[23693]) Exited with exit code: 1 http://sam.nipl.net/brace 11/9/09 8:53:00 AM [0x0-0x396396].org.webkit.nightly.WebKit[23671] Error occurred during initialization of VM 11/9/09 8:53:00 AM [0x0-0x396396].org.webkit.nightly.WebKit[23671] Incompatible minimum and maximum heap sizes specified 11/9/09 8:53:00 AM com.apple.launchd.peruser.501[171] ([0x0-0x396396].org.webkit.nightly.WebKit[23671]) Exited with exit code: 1 Under Safari I seem to be getting the same problems. http://ksturnpike.com 11/9/09 8:55:15 AM [0x0-0x383383].com.apple.Safari[23268] Error occurred during initialization of VM 11/9/09 8:55:15 AM [0x0-0x383383].com.apple.Safari[23268] Incompatible minimum and maximum heap sizes specified 11/9/09 8:55:15 AM com.apple.launchd.peruser.501[171] ([0x0-0x383383].com.apple.Safari[23268]) Exited with exit code: 1 http://sam.nipl.net/brace/ 11/9/09 8:56:54 AM [0x0-0x39a39a].com.apple.Safari[23708] Error occurred during initialization of VM 11/9/09 8:56:54 AM [0x0-0x39a39a].com.apple.Safari[23708] Incompatible minimum and maximum heap sizes specified 11/9/09 8:56:54 AM com.apple.launchd.peruser.501[171] ([0x0-0x39a39a].com.apple.Safari[23708]) Exited with exit code: 1 Just in case it might be helpful, I have the following plug-ins listed as installed.
