gdb says that it occurs in localtime.so.LC2. localtime.so.LC2 is the
result of running "ld -r -x" to mutilate the symbol table in localtime.so.
The error actually occurs in the static function tzload(). (The label
_tzload is removed because it is static and the label LC2 is renamed
because there is a bug.) The error occurs in code that used to work:
_tzload:
pushl %ebp
movl %esp,%ebp
subl $0x2328,%esp # lots of local variables
pushl %edi # use a stack page that was just allocated
The last instruction causes a SIGBUS.
