Thanks, but the information reported in the crash report is woefully
incomplete.  AFAICT, it says that find_interval crashed somewhere (it
doesn't tell on which line), and the cause of the crash was "Address
size fault".  It also says that this happened when Emacs tried to
insert some text into some buffer.

The way to provide more information is to run Emacs under a debugger,
and when it segfaults, collect the following information:

  . on which source line it crashes
  . which data causes the crash and why

Finding a reproducible recipe for the problem would also help.
