Is this a bug in execvp of std.process

[Cheng Wei]

#import std.process
void main() {
    execvp("ip", "route");
}

result:
Object "ute" is unknown, try "ip help".

That is the first two bytes are lost

Adding two spaces works:
#import std.process
void main() {
    execvp("ip", "  route");
}

Version 2.055, linux, 32bit

Thanks.
