Details:

// OS:
//   SunOS codesign10 5.9 Generic_118558-01 sun4u sparc
//
// gcc:
//   Reading specs from
/sun-local/gnu/bin/../lib/gcc/sparc-sun-solaris2.9/3.4.2/specs
//   Configured with: ../configure --with-as=/usr/ccs/bin/as
--with-ld=/usr/ccs/bin/ld --disable-nls
//   Thread model: posix
//   gcc version 3.4.2

// Testcase follows:

#include <stdarg.h>
#include <stdlib.h>


struct rel_record
{
    int _c;
};
typedef struct rel_record rel_record;

struct rel_table
{
    rel_record * _r;
};
typedef struct rel_table rel_table;

void
rel_add_records (rel_table * table, ...)
{
    va_list rp;
    rel_record r;

    va_start (rp, table);
    r = va_arg (rp, rel_record);
    while ( r._c )
      r = va_arg (rp, rel_record);
    va_end (rp);
}

int main( int argc, char *argv[] ) {
  rel_record r0 = { 12 };
  rel_record r1 = { 0 };

  rel_add_records (NULL, r0, r1); // ok

  // stdarg missuse breaks on SunOS
  rel_add_records (NULL, r0, 0); // segfaults
  return 0;
}
