What you should do is following:
1. Allocate all needed data, convert all D strings into C
strings, etc.
2. fork
3. exec immediately, not using anything from standard library
between 2 and 3.

It is child of my process after fork and before execl. No signal

And on this line on toStringz my program sometimes hangs.

The last backtrace shows that it hangs on the line:

Assign the result of toStringz to a char* variable and use that

But execl not goes to Seg.fault.
