I narrowed this down to this "ti->offset;" being uninitialized in the

Also this file
cpukit/score/cpu/arm/__tls_get_addr.c
I tried recompiling with this on the microblaze build with offset being
renamed to offseta.
This only caused a compilation error in the __tls_get_addr function.
So I think this variable is being used without being initialized or ever
changed.
Is it safe to just remove the offset variable?
No, it is not safe to remove the offset member. The offset member value
is provided by the caller of __tls_get_addr(). You have to check that
TLS_Index definition matches the GCC ABI. Do the sptls* tests run on
your system?
