Wes McKinney commented on ARROW-2256: ------------------------------------- I can't get fuzzing working at all on Ubuntu 19.04. The error looks like this {code} $ ./debug/arrow-ipc-fuzzing-test INFO: Seed: 3163524211 INFO: Loaded 1 modules (33926 guards): 33926 [0xd15918, 0xd36b30), INFO: Loaded 1 modules (143 inline 8-bit counters): 143 [0xd36b30, 0xd36bbf), INFO: Loaded 1 PC tables (143 PCs): 143 [0xd36bc0,0xd374b0), ERROR: The size of coverage PC tables does not match the number of instrumented PCs. This might be a compiler bug, please contact the libFuzzer developers. Also check https://bugs.llvm.org/show_bug.cgi?id=34636 for possible workarounds (tl;dr: don't use the old GNU ld) {code} There's a long thread about it here https://groups.google.com/forum/#!topic/llvm-dev/fnDXbyduLjw and https://github.com/google/oss-fuzz/issues/1042 > [C++] Fuzzer builds fail out of the box on Ubuntu 16.04 using LLVM apt repos > ---------------------------------------------------------------------------- > > Key: ARROW-2256 > URL: https://issues.apache.org/jira/browse/ARROW-2256 > Project: Apache Arrow > Issue Type: Bug > Components: C++ > Reporter: Wes McKinney > Priority: Major > Fix For: 0.14.0 > > > I did a clean upgrade to 16.04 on one of my machine and ran into the problem > described here: > https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=866087 > I think this can be resolved temporarily by symlinking the static library, > but we should document the problem so other devs know what to do when it > happens -- This message was sent by Atlassian JIRA (v7.6.3#76005)
