[Lazarus] Launching process from ServiceDaemon fails under Ubuntu x64 11.10+

Wed Mar 7 03:21:29 CET 2012

Up until a few days ago I was using my service daemon app (X) to launch a
console application (Y) worked flawlessly.  The service daemon monitors for
crashes and scale and can create instances at runtime.

I did a trunk update to both FPC and Lazarus and App Y got a bunch of
linker errors (see below) so I included interfaces unit and (Y) builds just
fine.

If terminal execution with parameters (Y) enters the program loop :-)
if executed from a Desktop App TProcess (Y) enters the program loop. :-)
If executed (X) inside a Service Daemon TProcess (Y) zombies and never
enters the program loop :-(

The service daemon is mission critical to my project and this is a pretty
serious issue.

Errors when I try to build Process app without Interfaces unit :

Options changed, recompiling clean with -B
/usr/bin/ld: warning: link.res contains output sections; did you forget -T?
