1071    On some systems, Emacs could crash due to problems with dynamic
1072    linking.  Specifically, on SGI Irix 6.5, crashes were reported with
1073    backtraces like this:

1086    (`rld' is the dynamic linker.)  We don't know yet why does this
1087    happen, but setting the environment variable LD_BIND_NOW to 1 (which
1088    forces the dynamic linker to bind all shared objects early on) seems
1089    to work around the problem.
