[Dovecot] lately pop3 with #define DEBUG needs GDB=1

[Diego Liziero]

I'm not sure when this happened.

In yesterday dovecot-1.1 hg if pop3 is compiled with DEBUG defined, it
needs GDB=1 otherwise it ends with:
Panic: Leaked file fd 4: dev 104.2 inode 3342766

Not sure if this can be caused by the fact that I call pop3 with a bash script.

protocol pop3 {
    mail_executable = /usr/libexec/dovecot/pop3.sh

inside I've something like
if [ x`id -un` = "xmyuser" -o x`id -un` = "xtestdovecot" ]
then
exec /usr/libexec/dovecot/pop3-new-test-release
else
exec /usr/libexec/dovecot/pop3
