Oh great, a new crash in Baloo::PostingCodec::decode(). :/
Oh whoops never mind, this is the one that's already been fixed! *** This bug has been marked as a duplicate of bug 367480 ***
Hm, not really, the first backtrace is from PostingCodec::decode. Unfortunately the backtrace is to incomplete to tell whats going wrong here. It is a bit fishy how this can go wrong, as it just allocates a vector the same size as the raw data from the DB and copies it. Source: https://cgit.kde.org/baloo.git/tree/src/codecs/postingcodec.cpp?id=2d31a8500edb755dbf253656f41a34c55223438e The only think I can think of is mdb_get returning something other than MDB_SUCCESS or MDB_NOTFOUND, val.mv_size is uninitialized and we try copy a random amount of data afterwards: https://cgit.kde.org/baloo.git/tree/src/engine/postingdb.cpp?id=2d31a8500edb755dbf253656f41a34c55223438e#n82 --- The second backtrace has a crash in the doctermscodec: https://cgit.kde.org/baloo.git/tree/src/codecs/doctermscodec.cpp?id=2d31a8500edb755dbf253656f41a34c55223438e#n76 The crash happens when the docterm array is reallocated to grow. 200 MByte (of d-ptrs) are about 25 million terms. Although thats not impossible, it is also somewhat unlikely. It may have the same reason as above, unchecked lmdb return code, attempting to decode random data.
Hmm, I thought we fixed the PostingCodec::decode() issue with Bug 367480 in Frameworks 5.51; this is from 5.50, before that fix went in.
No, only the *PositionCodec* - unfortunately, 367480 has instances of both.
(In reply to Stefan Brüns from comment #6) > No, only the *PositionCodec* - unfortunately, 367480 has instances of both. This one here has PostingCodec in KF5.50 and DocTermsCodec in KF5.51
Ahh, thanks for the clarification. It's probably at least partly my fault that 367480 has PostingCodec::decode() in it. I'll be more careful.
No worries, occasionally I'm that way, too ... I fear a lot of the "duplicates" also have backtraces for more than one of the codecs, so it would be impossible to do a clean sort.
@ Patrick - can you still reproduce one of the crashes? What happens when you do $> balooshow -d 2051 -i 2754878 $> balooshow -d 2051 -i 2754878 -x

The backtraces do not contain sufficient data, most importantly the document id. Without it, it is not possible to tell which database entry is responsible for the crash(es). The only other approach is to run something like 'find <dir> -type f -ls -exec balooshow -x \{\} \;' and see where it crashes.
I ran 'find /home/myusername -type f -ls -exec balooshow -x \{\} \;' on my system. No crash occured.
