--- Comment #4 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- In such a case you need to debug the system as a whole until you have isolated the bug to one component and can then report it to that component with evidence for where the bug is. It's quite possible pthread_exit could run into unwind info problems - make sure you have Olivier Hainque's patches <https://gcc.gnu.org/ml/gcc-patches/2014-11/msg02975.html> backported, together with my fix 2014-10-25 Joseph Myers <jos...@codesourcery.com> * config/rs6000/rs6000.c (rs6000_hard_regno_nregs_internal): Do not allow e500 double in registers not satisyfing SPE_SIMD_REGNO_P. before unwinding will work for e500v2 with 4.9.
