[Bug libstdc++/60936] [5/6/7 Regression] Binary code bloat with std::string
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60936 --- Comment #23 from __vic --- Jonathan, have you tried to merge you patch with mine? Yours lacks decoupling of string and iostream in c++11/cow-string-inst.o. I think it's a reason why code size was unaffected
[Bug c++/78929] Incorrect implementation of Refining Expression Evaluation Order for Idiomatic C++
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78929 --- Comment #2 from Ryou Ezoe --- My bad. §1.10 p18 still said "i++ + i" is undefined.

[Bug fortran/52473] CSHIFT slow - inline it?
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=52473 --- Comment #4 from Thomas Koenig --- Looking at the code, inlining cshift for a constant shift could already be a good idea. So, change b = cshift(b,1) + cshift(b,-1) to a = b b(1) = a(2) + a(n) b(2:n-1) = a(1:n-2) + a(3:n) b(n) = a(1) + a(n-1)

[Bug other/67520] libmpx should abort() instead of exit(255) on bound violation detection
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67520 Alexander Ivchenko changed: What|Removed |Added CC||aivchenk at gmail dot com --- Comment #2 from Alexander Ivchenko --- (In reply to Richard Biener from comment #1) > IMHO libraries should have a way to specify a custom handler (and default > that to abort maybe). Indeed exit (255) isn't very canonical. Addressed in: r243928 | aivchenk | 2016-12-26 18:14:06 +0300 (Mon, 26 Dec 2016) | 14 lines 2016-12-26 Alexander Ivchenko * mpxrt/libtool-version: New version. * mpxrt/mpxrt-utils.c (set_mpx_rt_stop_handler): New function. (print_help): Add help for CHKP_RT_STOP_HANDLER environment variable. (__mpxrt_init_env_vars): Add initialization of stop_handler. (__mpxrt_stop_handler): New function. (__mpxrt_stop): Ditto. * mpxrt/mpxrt-utils.h (mpx_rt_stop_mode_handler_t): New enum. * mpxrt/mpxrt.c (handler): Replace exit(255) with __mpxrt_stop function call. Now libmpx will call abort on bounds violations by default (User can restore previous behavior with CHKP_RT_STOP_HANDLER env variable)
