Rares Vernica commented on ARROW-2189: -------------------------------------- I did some tests and it does not look like these differences help with the issue. On the other hand, I compiled Arrow using {{g++-4.9}} and the issue is gone. > [C++] Seg. fault on make_shared<PoolBuffer> > ------------------------------------------- > > Key: ARROW-2189 > URL: https://issues.apache.org/jira/browse/ARROW-2189 > Project: Apache Arrow > Issue Type: Bug > Components: C++ > Affects Versions: 0.8.0 > Environment: Debian jessie in a Docker container > libarrow-dev 0.8.0-2 (Ubuntu trusty) > Reporter: Rares Vernica > Priority: Major > Attachments: Dockerfile, foo.cpp > > > When creating a {{PoolBuffer}}, I get a {{Segmentation fault}} when I use > {{make_shared}}. If I use the {{shared_ptr}} constructor of {{reset}}, it > works fine. Here is an example: > {code:java} > #include <arrow/builder.h> > int main() > { > arrow::MemoryPool* pool = arrow::default_memory_pool(); > arrow::Int64Builder builder(pool); > builder.Append(1); > // #1 > // std::shared_ptr<arrow::PoolBuffer> buffer(new arrow::PoolBuffer(pool)); > // #2 > // std::shared_ptr<arrow::PoolBuffer> buffer; > // buffer.reset(new arrow::PoolBuffer(pool)); > // #3 > auto buffer = std::make_shared<arrow::PoolBuffer>(pool); > } > {code} > {code:java} > > g++-4.9 -std=c++11 -larrow foo.cpp && ./a.out > Segmentation fault (core dumped) > {code} > The example works fine with {{#1}} or {{#2}} options. It also works if the > builder is commented out. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
