See test case:

module main2;

import tango.core.Vararg;

void vararg ( ... )
{

}

void main(char[][] args)
{
    vararg(12.23); // no crash
    echo();
}

void echo()
{
    scope(exit) vararg(12.23); // segf in line 5
}

I ported it to Phobos:
--------------------------
import std.c.stdarg;

void vararg ( ... )
{
}

void main(char[][] args)
{
    vararg(12.23); // no crash
}

void echo()
{
    scope(exit) vararg(12.23); // segf in line 5
}
------------------------
and it does not crash on Linux in 32 or 64 bit mode. Not for D1 nor D2. Maybe
it's a Tango specific problem.
