Hi Aurelien! (CC'ing Helmut Grohne since he has been seeing this issue in rebootstrap as well as Oleg Endo and Kaz Kojima as they are most likely interested in fixing the issue in gcc being gcc/sh upstream developers)

This will be available in the next upload. Wow, thanks a lot for tracking this down. Helmut Grohne has been seeing this issue in rebootstrap for a long time now and it was not until glibc 2.22 was uploaded when we saw this issue arise for native builds. I (and probably Helmut as well) are very glad this has been debugged now! I owe you a DebConf beer :). > It would be better instead if this can be fixed in GCC.

Maybe Oleg and Kaz could have a look at that. @Oleg: Should I file a gcc bug report? > [1] > https://buildd.debian.org/status/fetch.php?pkg=glibc&arch=sh4&ver=2.22-1&stamp=1457457915 > [2] http://anonscm.debian.org/cgit/pkg-glibc/glibc.git/commit/?id=eaa3701 > [3] https://gcc.gnu.org/ml/gcc-patches/2014-11/txt1S0Z0gdV3V.txt Adrian -- .''`.
