Bug 70947 – SIGBUS in PluginDatabase readTime on sparc/solaris 10

• Status: RESOLVED
• Resolution: WONTFIX
• Component: WebCore Misc.

[The Written Word]

Crashes in Source/WebCore/plugins/PluginDatabase.cpp:511 -
    resultTime = *reinterpret_cast_ptr<time_t*>(start);

Because start is not aligned on a 32 bit boundary.

Using memcpy fixes this for us. i.e.
     memcpy(&resultTime,start,sizeof(time_t));

Webkit > WebCore source on Github does not have "PluginDatabase.cpp" file:

https://github.com/WebKit/WebKit/tree/e4e4bba1f291d4773b907199bb5e6976d14c223d/Source/WebCore/plugins

Only reference to :PluginDatabase.cpp" exist in following file (in comment):
https://github.com/WebKit/WebKit/blob/e4e4bba1f291d4773b907199bb5e6976d14c223d/Source/WebCore/plugins/PluginData.h#L95

Which might be Not Applicable now.

There are two more reference to "PluginDatabase.cpp" but they are in WebkitLegacy (for Mac):

https://github.com/WebKit/WebKit/blob/1c6be76d456bf2887e32c236bdaf6f24c2b353ae/Source/WebKitLegacy/mac/WebView/WebViewData.h#L298

https://github.com/WebKit/WebKit/blob/5ddb4127ac4e4a104338422e546a1cdc7b698769/Source/WebKitLegacy/mac/WebView/WebView.mm#L1739

I think for Solaris / Spar port, the plugin support has been removed similar to other and I think this can be marked as "RESOLVED WONTFIX". Thanks!
