Output of compile command with -v -save-temps
This morning my Ubuntu 14.04 offered me an update of gcc package. I installed
it quite willingly since GNU guys usually know what they are doing. However
when I tried to compile my work project, as usual, I got following error:
lto1: internal compiler error: Segmentation fault

System is Ubuntu 14.04.
Output of version (-v) is attached.
temp files were not generated, probably because of the segfault. We are getting
no warnings while compiling the object files or during the link. Full list of
flags and other stuff we pass while compiling object files:
g++ -std=c++14 -DFORMAT_STRING_EXCEPT -Ilibs -Isrc -I/usr/include/jsoncpp
`pkg-config --cflags libosrm` -I`pg_config --includedir` -Wall -Wextra
-Wformat=2 -Wcast-qual -Wpointer-arith -Wstrict-aliasing "-DGIT_REV=\"`git
rev-parse HEAD`\"" -c -g3 -O0
