The problem is the fd_set call cmdlinedebugger.pp:waitforhandles. The handle
that is added is negative.

That handle traces back to the tprocess object, so that one works for
FreeBSD, but the handle is not ok.

That in turn seems to be created using "createpipestreams" and is 
named FParentInputStream;
in process.inc:47, which calls AssignPipe which is in linux.

I quick checked that, and that implementation seems sane, but I have to
rebuild FPC with debug info first before I can further get into that.

?MarcoV is confused here?

Traceback

(value of output.handle filedescriptor = -1077940440 in waitforhandles)
