Hi,
I am seeing a couple of core dump which point to std::strings like the ones below. The application is a multi-threaded application and compiled on sun4u 5.8 sparc with Sun Studio 11 C++ compiler 5.8 Patch 121017-16. The stack trace is being shown from a shared library which we built and is being used by our daemon service. I stack traces points to code where simple operation like clearing of vector<std::string> or creating or erasing std::string. The runtime environment is Solaris 5.10 sun4u sparc with SUNWlibC patches of 119963-19 and 119963-10.
We had an issue with clearing of vectors earlier whcih we solved by applying some compiler patches. This issue coming even after we have built the binaries with compiler patches. I have made sure that both the daemon and the shared library are all built with same compiler version. I would appreciate if any possible direction can be given for this.
