I managed to get further by usine -o but *not* -f (or -ff), since
using -o with -ff showed a child process’ log consisting exactly of:

--- SIGPWR (Power failure) @ 0 (0) ---
--- SIGXCPU (CPU time limit exceeded) @ 0 (0) ---
+++ killed by SIGINT +++

I believe it hung there.

Added to the logs were:

I don’t understand why it would want a debugging library here.
On the other hand, as good news, somehow the command works with
gij-4.4 and its library… but calling it as 'gcj-4.4' directly
still fails:

Yet…

root@aranym:~ # echo $?; ls -l x.class

I should note that gcj-4.4 used to work, and gcj-4.6 was TTBOMK never
tested. IIRC the ecj package was not recompiled since gcj-4.4 worked.

The following files match eclipse-ecj* on the filesystem:

655288 4964 -rw-r--r--   1 root     root      5068748 Sep 15  2011 /usr/lib/gcj/eclipse-ecj.jar.so

So this is probably not a problem with ecj, and possibly not even
with gcj, but with the precompiled classes? Thanks again for your
willingness to help debugging this. At the moment, db 5.1, db5.3,
libidn out of the core packages set alone are stalling on this…
