Bug ID: 95603
Summary: [11 Regression] sanitizer_linux.cpp:1880:16: error:
missing terminating ' character
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Keywords: build
Severity: normal
Priority: P3
Component: sanitizer
Assignee: unassigned at gcc dot gnu.org
Reporter: zsojka at seznam dot cz

Target Milestone: ---
Host: x86_64-pc-linux-gnu
Target: riscv64-unknown-linux-gnu
As originally reported in the thread [1], libsanitizer fails to build on
x86_64-pc-linux-gnu to riscv64-unknown-linux-gnu cross-compiler
configured as:
/repo/gcc-trunk//configure --enable-languages=c,c++ --enable-valgrind-
annotations --disable-nls --enable-checking=yes,rtl,df,extra --with-cloog --
with-ppl --with-isl --with-sysroot=/usr/riscv64-unknown-linux-gnu --build=x
86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --target=riscv64-unknown-linux
-gnu --with-ld=/usr/bin/riscv64-unknown-linux-gnu-ld --with-as=/usr/bin/
riscv64-unknown-linux-gnu-as --disable-multilib --disable-libstdcxx-pch --
prefix=/repo/gcc-trunk//binary-trunk-r11-767-20200601155732-gff7da2b5d62-
checking-yes-rtl-df-extra-riscv64
this is probably since [2]. The code would be probably accepted with
-std=gnu++14 or by patching the code not to contain the binary constants.
The error is:
