It happened using binaries from
http://download.savannah.gnu.org/releases/tinycc/.
Tried also via libtcc and the same happened: on win32, it works fine; on
win64, a segfault happens. Here's the code:
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include "libtcc.h"
char my_program[] = "\n";
int main(int argc, char **argv)
{
TCCState *s = tcc_new();
tcc_set_output_type(s, TCC_OUTPUT_MEMORY);
tcc_compile_string(s, my_program);
tcc_relocate(s, TCC_RELOCATE_AUTO); // <-- segfault here
return 0;
}
