about that strange call to a non-portable alloca()

[Dennis Clarke]

Probably best not to toss away cmd before the return .. oops :-\

in ./fuzz/main.c

    82  int main(int argc, char **argv)
    83  {
    84          int ret_val = 0;
    85          /* if VALGRIND testing is enabled, we have to call 
ourselves with valgrind checking */
    86          if (argc == 1) {
    87                  const char *valgrind = getenv("TESTS_VALGRIND");
    88
    89                  if (valgrind && *valgrind) {
    90                          size_t cmdsize = strlen(valgrind) + 
strlen(argv[0]) + 32;
    91                          char *cmd = malloc(cmdsize);
    92                          snprintf(cmd, cmdsize, 
"TESTS_VALGRIND="" %s %s", valgrind, argv[0]);
    93                          ret_val = ( system(cmd) != 0 );
    94                          free(cmd);
    95                          return ret_val;
    96                  }
    97          }
    98

That's better. Not pretty .. but seems to work on the linux boxen .. 
however on ye Solaris 10 sparc I see :

PASS: libidn_toascii_fuzzer
.
.
.
.... and then everything hangs .. for a while ... and then ...

PASS: libidn_tounicode_fuzzer
../build-aux/test-driver: line 107: 10364 Segmentation Fault      (core 
dumped) "$@" > $log_file 2>&1
FAIL: libidn_stringprep_fuzzer

So this isn't pretty.
