It's built with go 1.19.4.
Kernel is Linux 6.0.0-3-riscv64 #1 SMP Debian 6.0.7-1 (2022-11-05) riscv64 (riscv64)
I think it's HiFive Unmatched board.
Comment From: mengzhuo
cc @golang/riscv64 It looks real problem to me. p.s. The linux/riscv builders are using Ubuntu 21.04 without llvm, all the asan related tests are skipped.
Comment From: bcmills
Looks like this test was enabled for riscv64 in CL 375256 (Go 1.19).

Looks like this test was enabled for
riscv64in CL 375256 (Go 1.19).
Then there's something broken. We can build Go 1.19 before. https://buildd.debian.org/status/logs.php?pkg=golang-1.19&arch=riscv64

What version of the C compiler are you using? Thanks.

Hi,

dfbecc06e73b79aaeee4220b3e760cbd76050ae5 is the first bad commit

misc/cgo/testsanitizers: fix code to detect gcc version correctly
The current implementation of compilerVersion incorrectly gives an
error message that the compiler version is too old even though the
system has a recent compiler. This happens for specifically for the
gcc compiler and causes ASAN tests to be skipped.
Replacing -v with gcc dump version options seems to fix it. Running
./testsanitizers.test -test.v now shows the ASAN tests being run.

I can confirm gcc-12 is the culprit, gcc 11 passed all the tests.
Why asan accessing an unknown memory?

Comment From: mengzhuo
@zhsj This might be a bug from libasan8.
asan 12.2.0 using SHADOW_OFFSET by 0xd55550000
static const u64 kRiscv64_ShadowOffset64 = 0xd55550000;
...
#elif SANITIZER_RISCV64
#define SHADOW_OFFSET kRiscv64_ShadowOffset64
...
#define MEM_TO_SHADOW(mem) (((mem) >> SHADOW_SCALE) + (SHADOW_OFFSET))
this should be (mem >> 3) + 0xd55550000
However I found that libasan8's SHADOW_OFFSET is 0x20000
0x129996 <x_cgo_init+116> srli s1,s2,0x3
0x12999a <x_cgo_init+120> lui a5,0x20000
0x12999e <x_cgo_init+124> add a5,a5,s1

I was investigating this issue and found kRiscv64_ShadowOffset is changed in libsanitizer/asan/asan_mapping.h to 0xd55550000 while value in gcc/config/riscv/riscv.cc remains the original value of 0x20000000 (1<<29).
This issue is fixed in https://github.com/gcc-mirror/gcc/commit/21a07620f4bfe38f12e6d5be8b1eeecc29fa6852 (one day before I discovered the issue and gcc-mirror then was out-of-date), and all Go tests passed with cherry-picked GCC 13.1.1 on Arch Linux riscv64.
Sorry for the late response. Thanks @mengzhuo and @yuzibo for their help, and @andreas-schwab for fixing. The issue may be closed now unless I missed something.

Confirmed. It's also fixed in gcc 12.

The libasan of debian port is not fixed in 20221225T084846Z, I will lock the version of libasan in visionfive2 builder.
Closed.
