--- Comment #12 from John Soo <john.soo+gcc-bugzilla at arista dot com> --- I think the general problem in that issue is that ARG_MAX is not respected when the driver (or any subprocess) execs things on linux. I think that it is not the same as the original issue here, though. > I don't know if its going to be helpful to see that patch as a guide Do you think using response files like in pex-win32.c in pex-unix.c could help? I tried this out and it seems like this may not solve all the ARG_MAX problems.
