I know .. I was looking at that and thinking .. hold on .. no way can p 
be NULL on that call.

n0$ openssl dgst -sha256 ../src/libidn-1.34.tar.gz
SHA256(../src/libidn-1.34.tar.gz)=

n0$ cd libidn-1.34_SunOS5.10_sparcv9.003
n0$ wc -l lib/nfkc.c
    1112 lib/nfkc.c

Guess what ... a previous version is getting dragged into the mix here :

n0$ wc -l ../libidn-1.33_SunOS5.10_sparcv9.001/lib/nfkc.c
    1124 ../libidn-1.33_SunOS5.10_sparcv9.001/lib/nfkc.c
n0$

n0$ tail -20 ../libidn-1.33_SunOS5.10_sparcv9.001/lib/nfkc.c
 * @len: length of @str array, or -1 if @str is nul-terminated.
 *
 * Converts a UCS4 string into canonical form, see

uint32_t *
stringprep_ucs4_nfkc_normalize (const uint32_t * str, ssize_t len)
{
  char *p;
  uint32_t *result_wc;

  p = stringprep_ucs4_to_utf8 (str, len, 0, 0);
  result_wc = _g_utf8_normalize_wc (p, -1, G_NORMALIZE_NFKC);
  free (p);

  return result_wc;
}
n0$

ah ha !

No check for p being NULL there.

I have previous libidn 1.33 in /usr/local/lib and that must be getting 
caught up in this mess.

Oh .. this is loads of fun to unravel.

I will set aside libidn.so.11.6.16 in /usr/local/lib and start over.

Gets even better .. there are system libs in the way :

n0$ ldd ./lib/.libs/libidn.so.11.6.18
        libintl.so.8 =>  /usr/local/lib/libintl.so.8
        libc.so.1 =>     /lib/64/libc.so.1
        libiconv.so.2 =>         /usr/local/lib/libiconv.so.2
        libm.so.2 =>     /lib/64/libm.so.2
        /lib/sparcv9/../libm/sparcv9/libm_hwcap1.so.2
        /platform/SUNW,SPARC-Enterprise/lib/sparcv9/libc_psr.so.1
n0$ ldd ./examples/.libs/example
        libidn.so.11 =>  /usr/lib/64/libidn.so.11
        libintl.so.8 =>  /usr/local/lib/libintl.so.8
        libc.so.1 =>     /lib/64/libc.so.1
        libiconv.so.2 =>         /usr/local/lib/libiconv.so.2
        libm.so.2 =>     /lib/64/libm.so.2
        /lib/sparcv9/../libm/sparcv9/libm_hwcap1.so.2
        /platform/SUNW,SPARC-Enterprise/lib/sparcv9/libc_psr.so.1
n0$

However maybe I need to set LD_LIBRARY_PATH ?

n0$ LD_LIBRARY_PATH=`pwd`/lib/.libs ldd ./src/.libs/idn
        libidn.so.11 => 
/usr/local/build/libidn-1.34_SunOS5.10_sparcv9.003/lib/.libs/libidn.so.11
        libintl.so.8 =>  /usr/local/lib/libintl.so.8
        libiconv.so.2 =>         /usr/local/lib/libiconv.so.2
        libc.so.1 =>     /lib/64/libc.so.1
        libm.so.2 =>     /lib/64/libm.so.2
        /lib/sparcv9/../libm/sparcv9/libm_hwcap1.so.2
        /platform/SUNW,SPARC-Enterprise/lib/sparcv9/libc_psr.so.1
n0$

OKay if I hide the previously installed libidn-1.33 and also set 
LD_LIBRARY_PATH to point to the build dir and then ./lib/.libs well gee 
I finally get :

Undefined                       first referenced
 symbol                             in file
alloca                              main.o

So this is progress I think.

Loads of fun.
