[Bug libstdc++/79980] New: Possible bug in codecvt.cpp bitmask setting code

Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: thakis at chromium dot org Target Milestone: --- codecvt.cpp has this snippet: if (read_utf16_bom(from, mode) == little_endian) mode = codecvt_mode(mode & little_endian); That probably should

[Bug c++/64816] gcc claims that constructor is private when it should be accessible

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64816 --- Comment #1 from thakis at chromium dot org --- (Here's a patch with a libc++-side workaround: http://reviews.llvm.org/D7201 But it'd be good to fix this in the compiler too, of course.)

[Bug c++/63872] -Wunused-local-typedefs warns incorrectly on a typedef that's referenced from a template

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63872 --- Comment #2 from thakis at chromium dot org --- I think warning on unused typedefs in local classes is generally a useful feature, not a bug. The bug here is that it's warning on a typedef in a local class that is being used.

[Bug preprocessor/60875] `_Pragma("message \"foo\")"` doesn't work in expression contexts.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60875 --- Comment #2 from thakis at chromium dot org --- That only works on declarations, not in an expression, right? (We do have a workaround that works with gcc. But "pragma message" matches the semantics of what we want to do, and it
