libsigsegv-2.1 hangs on configure due to a mishandling of the fault handler. The patch suggests that the error stems from the fact that the code was written for <darwin-5.5 (<OSX 10.1.5). Since we don't support those configurations, we can apply the patch universally.
Created attachment 41848 [details, diff] Patch for configure lock
Patch applied, builds, and tests pass on 10.3.5. Can be keyworded ~ppc-macos. I'll take care of it as soon as I can get to a machine with non-broken sandbox.
In CVS. Thanks Joe.
Closing out bugs that've been resolved for a while now...
