It looks as if there is a difference of 1 ULP.
Thus, one option would be to permit both results ("str /= ... and str /= ...").

Or, alternatively and possible better: to understand why there is now a ULP
difference, which didn't exist in GCC 4.9.

Yes, can you please debug this?
Try e.g. GCC 5 compiled testcase against 4.9 libgfortran or vice versa, if the
difference is in the binaries, do side-by-side debugging of the 4.9 and 5
version in the debugger and watch where things differ, if it is on the library
side, identify which call differs?

This is not a regression. In 4.9 and previous to r214187 on trunk, the test
was unresolved:

sqrtl is not available on hpux. It seems at some point before r214253
the test started running, probably using sqrtq from libquadmath. I'm not
sure why this happened.

The current code now uses the libcall, _U_Qfsqrt, in libm.

The change from sqrtl to _U_Qfsqrt occurred in r214211:

* options.c (gfc_init_options_struct): assert that the frontend sets
