0 at 0.so.1 only exists in ld.so.1(1) as far as I know. Perhaps something
similar for Rogers library.
NOTES
...
The user compatibility library /usr/lib/0 at 0.so.1 provides a
mechanism that establishes a value of 0 at location 0. Some
applications exist that erroneously assume a null character
pointer should be treated the same as a pointer to a null
string. A segmentation violation occurs in these applica-
tions when a null character pointer is accessed. If this
library is added to such an application at runtime using
LD_PRELOAD, the library provides an environment that is sym-
pathetic to this errant behavior. However, the user compati-
bility library is intended neither to enable the generation
of such applications, nor to endorse this particular pro-
gramming practice.
