[Samba] nsswitch segfaults with Samba 3.0.21 on Solaris 9

[J S]

Compiling with the --enable-developer and --enable-debug options, the
compiler complains about calling malloc directly on solaris during nsswitch
then fails.  This is gcc 3.3.2 on Solaris 9.

Here are the configure flags:

./configure CPPFLAGS="-I/export/build/ldap/include -I/usr/local/include
-I/usr/local/BerkeleyDB.4.2/include -I/usr/local/ssl/include
-I/export/build/krb5/include" LD_LIBRARY_PATH="-L/export/build/ldap/lib
-L/usr/local/lib -L/usr/local/BerkeleyDB.4.2/lib -L/usr/local/ssl/lib
-L/export/build/krb5/lib" LDFLAGS="-L/export/build/ldap/lib -L/usr/local/lib
-L/usr/local/BerkeleyDB.4.2/lib -L/usr/local/ssl/lib
-L/export/build/krb5/lib -R/export/build/ldap/lib -R/usr/local/lib
-R/usr/local/BerkeleyDB.4.2/lib -R/usr/local/ssl/lib
-R/export/build/krb5/lib" --prefix=/export/build/smb321 --enable-debug
CC=gcc --with-ads --enable-debug --with-winbind --enable-developer

And here's the warning.
