I remember now.  Believe it or not, it was a bug in the kernel,
triggered by a bug in glibc.  The filebuf structure in elf/dl-load.c
was not sufficiently aligned, and this caused a mis-aligned load to be
put in a delay slot of a branch within the switch statement.  The
kernel, due to a bug, failed to emulate the mis-aligned load properly,
and so we ended up with garbage in the register, which caused us to
exit the loop too early.
