Change subject: IMPALA-7272: Fix crash in StringMinMaxFilter ...................................................................... Patch Set 1: (1 comment) http://gerrit.cloudera.org:8080/#/c/11650/1/be/src/runtime/mem-pool.h File be/src/runtime/mem-pool.h: http://gerrit.cloudera.org:8080/#/c/11650/1/be/src/runtime/mem-pool.h@260 PS1, Line 260: uint8_t* ALWAYS_INLINE Allocate(int64_t size, int alignment) noexcept { > Good to hear that DFAKE_SCOPED_LOCK() is catching the problem. After digging in more, it looks like the problem is actually related to codegen - even correct uses of MemPool with the DFAKE_MUTEX from a codegen'd function cause crashes and disabling codegen fixes the crashes. I'm not sure what's going on - there isn't any sort of error and the backtraces from the crashes are useless - but I'm continuing to dig in. Any thoughts on what might be happening? -- To view, visit http://gerrit.cloudera.org:8080/11650 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I751cad7e6b75c9d95d7ad029bbd1e52fe09e8a29 Gerrit-Change-Number: 11650 Gerrit-PatchSet: 1 Gerrit-Owner: Thomas Marshall <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Michael Ho <[email protected]> Gerrit-Reviewer: Philip Zeyliger <[email protected]> Gerrit-Reviewer: Thomas Marshall <[email protected]> Gerrit-Comment-Date: Thu, 11 Oct 2018 23:17:45 +0000 Gerrit-HasComments: Yes
