Ocilib Crashing at Multithreading data race #359

I am working on the stress tool to connect to oracle db and manipulate data. But at the stress test, I am hit with a tool crashing in Linux with a segmentation fault.

I am creating 100 threads and each thread does a bunch of SQL query.

I have written a wrapper class TOraResultSet which encapsulates ocilib::Statment and ocilib::ResultSet as unique_ptr and TOraConn which returns this TOraResultSet pointer to where its called.

Can you please guide or help with what could be wrong with ocilib?

Hi,

Did you use the flag Environment::Threaded when calling Environment::Initialize() ?

Regards,

Vincent

I am able to reproduce in windows, the SmartHandler facing unhandled exception when the Statement goes out of scope.
