Error description
The tls_model __attribute__ settings is not used for a specific configuration. When accessing TLS data within a thread local struct that is >32kb in size, incorrect data is returned.
Local fix
N/A
Problem summary
PROBLEM DESCRIPTION: Incorrect code is sometimes generated when any one TLS data structure is >32kb. In these cases, setting the tls_model attribute does not not affect the model setting used by the compiler. USERS AFFECTED: Those using TLS with fast relocation access.
Problem conclusion
The issue was corrected, and TLS data structures >32kb are automatically made to use non-fast relocation access models.
Temporary fix
