Nope. It didn't trigger on 1.12 because it wasn't linked with GNU ld.
The problem is that GNU ld sets the dynamic linker as
/usr/lib/libc.so.1, whereas Sun ld sets it to /usr/lib/ld.so.1. Even
though Sun officially supports both, according to a friend of mine at
Sun, the one chosen by GNU ld fails because it assumes the environment
contains at least one non-NULL entry. My friend is working on a fix
for Solaris/x86 libc; I'm not sure we (GNU developers) are going to
fix GCC or GNU ld, or both, or neither, since the work-around is
simple: just link the program using
`-Wl,--dynamic-linker,/usr/lib/ld.so.1', or use Sun ld, or make sure
the environment is never empty, or wait for a patch from Sun.
