Comment #4 on issue 34091 by ClusterFuzz-External: assimp:assimp_fuzzer: Direct-leak in Assimp::SortByPTypeProcess::Execute
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=34091#c4

This crash occurs very frequently on linux platform and is likely preventing the fuzzer assimp_fuzzer from making much progress. Fixing this will allow more bugs to be found.

If this is incorrect, please file a bug on https://github.com/google/oss-fuzz/issues/new
