[Bug other/108464] [13 Regression] Broken -fdebug-prefix-map since r13-3599
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108464 --- Comment #6 from Orion Poplawski --- So, there was quite the initial flurry of activity here and then nothing. Any chance we could get some more movement here? It's breaking a ccache test for one. Thank you.

[Bug c/79677] Weird handling of -Werror=

--- Comment #10 from Orion Poplawski ---
I'm not sure how I'm practically supposed to handle this. In this case, for
one sub-directory upstream adds -Wno-format to the flags:
./Utilities/KWIML/test/CMakeLists.txt:set(CMAKE_${lang}_FLAGS
"${CMAKE_${lang}_FLAGS} -Wno-format")
Is this still a bug in gcc?

--- Comment #5 from Orion Poplawski ---
With gcc 7.0.1-0.10.fc26 I'm starting to see errors like:
cc1plus: error: -Wformat-security ignored without -Wformat
[-Werror=format-security]
If this is intended, we're going to need to fix redhat-rpm-config to change:
%__global_compiler_flags -O2 -g -pipe -Wall -Werror=format-security
-Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong
--param=ssp-buffer-size=4 -grecord-gcc-switches %{_hardened_cflags}
to add -Wformat.

[Bug c++/61294] [4.9 Regression] erroneous memset used with constant zero length parameter warning
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61294 --- Comment #3 from Orion Poplawski orion at cora dot nwra.com --- Hmm, now all of a sudden I don't seem to be able to reproduce this. Thanks for your comments though. I play around if it re-appears. The problem was compounded by the use of -Wl,--fatal-warnings so it was preventing linkage.

With gcc 4.4.5 (compiles without warnings with -Wall):
c(0x7fff16e86a00), d(0x7fff16e868d0)=1.00

c(0x7fff5411f340), d(0x7fff5411f210)=0.00
It appears that the right hand side pointer is being incremented at the rate
of its promoted size. If you remove the * s from the increment line, the
code works as expected. Same problem with 32-bit and 64-bit machines.
