Building on Linux x86_64 (SLES15.5) with ASAN enabled (--enable-asan ) works and the created JDK can be used for basic runs like 'java -version'.
But when running jdk :tier1 jtreg tests, the following issue shows up :

# SIGSEGV (0xb) at pc=0x0000000000000000, pid=78762, tid=79062
#
# JRE version: OpenJDK Runtime Environment (25.0.0.1) (build 25.0.0.1-internal-adhoc.myuser.jdk)
# Java VM: OpenJDK 64-Bit Server VM (25.0.0.1-internal-adhoc.myuser.jdk, mixed mode, sharing, tiered, compressed oops, compressed class ptrs, g1 gc, linux-amd64)
# Problematic frame:
# C [libasan.so.8+0x83e62]

siginfo: si_signo: 11 (SIGSEGV), si_code: 1 (SEGV_MAPERR), si_addr: 0x0000000000000000

Is this related to a 'bad' ASAN version, or can we do something about it in OpenJDK itself or in jtreg ?
