You need to call toArgz and toStringz before the fork, since 
either of those can be in TLS. Test with:


string cmd = "echo";
string[] args1 = ["hello"];
string[] args2 = [];

void main()
{
   spawnProcess(cmd, args2);
   spawnProcess(cmd, args1);
   args ~= "World";
   spawnProcess(cmd, args2);
}


I'm not exactly sure what is up, but in one of my projects I had 
this problem. I solved it by just making all the string[]s into 
__gshared.

Cheers, Jakob.
