I couldn't duplicate the problem with binutils 2.19.1-1 and gcc-4.3
4.3.3-10, or with my own binutils build on two different systems.

The above shouldn't happen as the text size of FileManager.o is well below
the size where a 17-bit branch can't reach the stub table.  Possibly, the
stub table is full.  On the otherhand, the "0000f9bf_memcpy@@GLIBC_2.2+0"
string looks garbled.  So, this may be another form of the SMP memory
corruption that causes the segvs, particularly if it isn't reproducible
on the build system.

The suggestion to "recompile with -ffunction-sections" is somewhat
misleading.  While -ffunction-sections may help sometimes, in other
cases it may be necessary to play with the ld --stub-group-size=N
option, or to compile with -mlong-calls.
