dtrace -G uses shell to execute gcc:
call("gcc -fPIC -c " + fn + " -o " + filename, shell=True)
This makes directories with spaces problematic:
% mkdir a\ directory
% cd a\ directory
% touch test.d
% ../dtrace -G -s $PWD/test.d
gcc: directory/test.o: No such file or directory
Better way is to use python equivalent of execlp(3) or execvp(3).

I made it so that call passes a list of arguments so that spaces aren't a
problem in:
commit c0d0d86876a3763492b3f4054961e9c850e9c216

PR 9850, use a list of arguments for call.
But you will still have to quote things like $PWD on the command line to get
them as whole arguments to python (otherwise the shell seems to split them into
multiple arguments anyway). So using this now works:
../dtrace -G -s "$PWD/test.d"
as does
../dtrace -G -s ../a\ directory/test.d
Is this enough?
I am not sure how to get the behaviour you want without quoting the $PWD
variable in the shell.

Hmm, not my shell (zsh)... But others realy do so.

Yep, this is enough.
