Blake Bender commented on GEODE-8436:
-------------------------------------
Thanks for investigating, Alberto. I'll run a CI pass with GEODE-8436
reapplied and GEODE-8231 reverted, and see if it looks better. If so, the next
step is most likely to go ahead and do the same thing in develop, but I'll get
back to you beforehand.

> Key: GEODE-8436
> URL: https://issues.apache.org/jira/browse/GEODE-8436
> Project: Geode
> Issue Type: Bug
> Components: native client
> Reporter: Alberto Bustamante Reyes
> Assignee: Alberto Bustamante Reyes
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.14.0
>
> Attachments: main.cpp

> I have seen a problem when "PdxInstanceFactory::create()" is called by
> several threads that are registering the same new pdx type.
> The core is produced here:
> {code}
> void PdxInstanceImpl::toDataMutable(PdxWriter& writer) {
> auto pt = getPdxType();
> std::vector<std::shared_ptr<PdxFieldType>>* pdxFieldList =
> pt->getPdxFieldTypes();
> {code}
> The problem is that "getPdxType()" returns nullptr, so in the next line,
> there is segmentation fault when calling "pt->getPdxFieldTypes()".
> The issue can be reproduced using the attached client, and executing it using
> 8 threads. This is the stack got in gdb:
> {code}
