I found a hint.

When Lazbuild is used to build the project, fpcres doesn't write any output to 
the console, (I verified this with strace) but exits with exit code 2:

When the compiler command-line is executed directly, fpcres does output a message:

So it is lazarus/lazbuild (probably the TProcess class) that causes
the message to be "eaten" by somehow not treating the standard error 
file descriptor correctly.

I verified that the FPC compiler does not change any of the file descriptors
when executing fpcres.
