Never did, it's our illumos distro, but I may have valgrind.
Can you help on this?

Oggetto: Re: Squatter core dump
That is odd. I don't think we touched that part of the code for a long while. It might be that there is some other code corrupting the memory where SquatIndex is located.Would you have a chance to run squatter with valgrind?On Fri, May 7, 2021, at 3:23 PM, Gabriele Bulfon via Info wrote:The problem lies here:/* Add 'doc_ID' to the list of document IDs for word 'word_ptr'in the "all documents" trie. */static int add_word_to_trie(SquatIndex * index, char const *word_ptr,int doc_ID){WordDocEntry *word_entry = index->word_doc_allocator++;word_entry->doc_ID = doc_ID;add_to_table(index, word_ptr, SQUAT_WORD_SIZE - 1, word_entry);return SQUAT_OK;}Looks like word_entry (index->word_doc_allocator++) does not point to a valid memory area.What may have happened?GabrieleSonicle S.r.l. : http://www.sonicle.comeXoplanets : https://gabrielebulfon.bandcamp.com/album/exoplanetsDa: Gabriele Bulfon via Info <info@xxxxxxxxxxxxxxxxxx>

Oggetto: Squatter core dumpHi,I could set up a cloned machine with a specific big mailbox causing core dump every time squatter tries to rebuild the index.So I rebuilt the squatter binary with debug info (-g) and here is the gdb back trace for 2.5.11 sources:(gdb) bt#0 0x00000000004067a7 in add_word_to_trie (index=0x652600, word_ptr=0xffffdf7fb949312d <error: Cannot access memory at address 0xffffdf7fb949312d>, doc_ID=28651) at imap/squat_build.c:790#1 0x0000000000407ce1 in dump_index_trie_words (index=0x652600, first_char=191, result_offset=0xffffdf7fffdfdcfc) at imap/squat_build.c:1449#2 0x0000000000408177 in index_close_internal (index=0x652600, OK=1) at imap/squat_build.c:1589#3 0x00000000004085c8 in squat_index_finish (index=0x652600) at imap/squat_build.c:1695#4 0x0000000000404d74 in squat_single (state=0x41ddc0, incremental=0) at imap/squatter.c:484#5 0x0000000000405331 in index_me (name=0xffffdf7fffdfe920 "sonicle.com!user.test^big", matchlen=0, maycreate=0, rock=0xffffdf7fffdff924) at imap/squatter.c:636#6 0x00000000004056ee in main (argc=7, argv=0xffffdf7fffdff968) at imap/squatter.c:746I don't know if this is the same reason why cyrus.squat is always rebuilt from scratch on many big mailboxes.Hope this may help close this long awaited resolution.I can patch & rebuild binaries easily on this cloned test machine, if you can give me directions on where the problem may be.Thanks!GabrieleSonicle S.r.l. : http://www.sonicle.comeXoplanets : https://gabrielebulfon.bandcamp.com/album/exoplanets
