您需要设置环境变量来请求核心转储

You need to set environment variable to request coredumps

export ASAN_OPTIONS=abort_on_error=1

此应该确实是默认值，但是由于历史原因，ASan只会以非零错误代码退出。

This should really be default but due to historic reasons ASan just exits with non-zero error code instead.

在64位系统上，您可能需要添加

On 64-bit systems you might need to add

export ASAN_OPTIONS=...:disable_coredump=0:unmap_shadow_on_exit=1

（核心转储默认情况下处于禁用状态，因为担心它们会太大）。

(coredumps are disabled by default there, in fear that they will be too large).

有关标志的完整列表您可以看到 Asan Wiki 。
