"Undefined subroutine &main:: called." from nowhere??

This happens when my program ends:

$ perl -d tools/dbdiff [..arguments..]
[... set break on last line of tools/dbdiff ...]
[... c ...]
[... various regular no-error program output ...]
main::(tools/dbdiff:449): print STDERR "Exiting\n";
DB<2> s
Exiting
Undefined subroutine &main:: called.
END failed--call queue aborted at tools/dbdiff line 1.
Dbase::CODE(0x8633f44)(/opt/ess/pp01/src/datenbank/dbperl/Dbase.pm:859):
859: print STDERR "PreEnd1\n";

OK. Needless to say, line 1 contains of "#!/usr/bin/perl" and nothing else.

So which *CENSORED* unsinglesteppable part of Perl decided to do this??

$ perl -v
This is perl, v5.8.4 built for i386-linux-thread-multi

Any help on where to dig further would be appreciated.

Addendum:

.... and it stops here (endless loop, non-interruptible) when I do this
with PERLDB_OPTS="NonStop AutoTrace".

Time to recompile with debugging support. With my luck the problem will
then go away.

Interesting. :-/
