JVM crashes with grpc-netty-shaded 1.67.1 and alpine docker image #11660

Open jehervy opened 1 day ago

jehervy commented 1 day ago

An update of com.google.cloud dependency (which depends on grpc-netty-shaded:1.67.1) with a image built from eclipse-temurin:21-jre-alpine leaded to a segmentation fault:

# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x00000000000204b6, pid=1, tid=17
#
# JRE version: OpenJDK Runtime Environment Temurin-21.0.5+11 (21.0.5+11) (build 21.0.5+11-LTS)
# Java VM: OpenJDK 64-Bit Server VM Temurin-21.0.5+11 (21.0.5+11-LTS, mixed mode, sharing, tiered, compressed oops, compressed class ptrs, g1 gc, linux-amd64)
# Problematic frame:

#
# Core dump will be written. Default location: /core.%e.1.%t
#
# An error report file with more information is saved as:

As a workaround we had to downgrade to grpc-netty-shaded:1.65.1

Full error log: hs_err_pid1.log

Ths is happening on eclipse-temurin:17 also:

eclipse-temurin:17?? That isn't Alpine. Alpine issues are common, but Ubuntu Temurin is very normal. I do see the address of the crash is the same, so likely related.

We either need to reproduce and try with various versions of netty-tcnative to try to find the change. Or we pull out objdump.

Investigation assuming the two errors are unrelated... (Spoiler: doesn't seem Alpine-specific.) Following the typical Alpine flow, it doesn't indeed seem related to glibc compatibility.

$ podman run --rm -it docker.io/eclipse-temurin:21-jre-alpine /bin/sh

isnan and isinf are new. But no more need for libunwind:
