There is a very small possibility of a fault only if lazy task swapping is
enabled on a processor revision that has this fault. The bug relates to a
problem restarting the load multiple instruction if a page fault occurs after
loading one or more registers, and page faults will only occur in RISC OS
application memory when lazy task swapping is in use. This may explain why
early versions of the SharedUnixLibrary disabled lazy taskswapping, but this
has now been removed, however it would appear that the version of GCC used to
build Firefox can generate LDMIB instructions which may be susceptible.

Check if lazytask swapping is enabled using OS_AMBControl 5 -1, R1 will be
1 if it is enabled. Use OS_AMBControl 5 <0|1> to disable/enable if you wish
to check if any crashes experianced are due to this problem. I think it is
unlikely however.
