Either fix your code, or use socketpair() instead of pipe().

I'll try to read about socketpair(), but I'd prefer not to have to rewrite the code too much.


I have replaced the two lines

  pipe (tochild);
  pipe (fromchild);

by

  socketpair (AF_UNIX, SOCK_STREAM, PF_UNSPEC, tochild);
  socketpair (AF_UNIX, SOCK_STREAM, PF_UNSPEC, fromchild);

(plus an additional "#include <sys/socket.h>") and this seems to work. The Fink texmacs package is now patched accordingly. Texmacs has a maple plugin that uses the same construct. Last I heard, this plugin doesn't work on Tiger either, but I can't test it, because I don't have maple.

I am still curious what exactly is causing this strange behavior on Tiger. If I get a little closer, I'll file a bug.
