[Dovecot] Segmentation Fault in doveadm move under Solaris 10
Hi all
I want to move mails from folder test-ein to another folder test-aus
with the new "doveadm move" command in dovecot 2.0.12. When I try the
following I get a "Segmentation Fault" after the mail was copied to
the new folder:
# doveadm -v -f flow search -u g033 mailbox test-ein all
56779e33a911b84db22900005451a966 1
# doveadm -v -f flow search -u g033 mailbox test-aus all
# doveadm -v -f flow move -u g033 test-aus mailbox test-ein all
Segmentation Fault
# doveadm -v -f flow search -u g033 mailbox test-aus all
57779e33a911b84db22900005451a966 26
# doveadm -v -f flow search -u g033 mailbox test-ein all
56779e33a911b84db22900005451a966 1
The mail now is in both the source folder and the destination folder.
With truss under Solaris 10 we can see what happens (only the last few
lines are shown):
