[jira] [Commented] (ARROW-2403) [C++] arrow::CpuInfo::model_name_ destructed twice on exit

["Uwe L. Korn (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-2403?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16428384#comment-16428384 ] 

Uwe L. Korn commented on ARROW-2403:
------------------------------------

I haven't seen this yet. I had once the problem where other global constants got deallocated twice but that was due to the fact that parquet-cpp was once linked dynamically and once statically in the same process.

> It appears that the destructor for this static string is being called twice by {{__run_exit_handlers}} and I don't know why.  Anyone else seen this?
> For programs which are otherwise normal, this causes (nondeterministic) aborts on exit when glibc detects the double free.  It might be specific to pyarrow, I haven't tried reproducing it with a C program that links with libarrow.so yet.
