In a small case I wrote to duplicate it, it seems a linker bug.
I.e. if you swap the two objects, it works.

Martin

A new problem.  I filed QXCR1000848848:
Invalid dynamic relocation needed for read-only section for TLS -ipo

One workaround might be using [+tls|http://docs.hp.com/en/10946/options.htm#opt+tls]=static.
