>Description:
the GNU C++ compiler in FreeBSD doesn't correctly handles "__attribute__((constructor))", but it works if I use C compiler instead.
>How-To-Repeat:
this is the demo program:
#include <stdio.h>
int g_int = 0;
void init() __attribute__((constructor));
void init()
{
g_int = 1;
}
int main(int argc, char** argv)
{
if (g_int == 1)
printf("__attribute__((constructor)) work!\n");
else
printf("__attribute__((constructor)) not work!\n");
return 0;
}
if the source program name is test.cpp and use command "c++ test.cpp" to compile it, "__attribute__((constructor))" hasn't effect, but if the source program name is test.c, then use command "cc test.c" the compile it, it works!
>Fix:
I think some utilities in FreeBSD are inconsistent, it has different version of utilities for C and C++, need update these utilities.
