Additional information

We suspect it is the same check/comment https://github.com/nodejs/node/blob/5b6091ce31068e1c86f863273cdd397ecb47e3b7/deps/v8/src/base/platform/platform-aix.cc#L194-L199 as referenced in https://github.com/nodejs/node/pull/62470.

首先在 AIX 上运行 out/Release/node --experimental-wasm-modules .../test/wpt/test-wasm-jsapi.mjs，并检查 deps/v8/src/base/platform/platform-aix.cc 第 194-199 行附近的代码。比较失败时的控制台输出和关联的 CI 运行记录，以确定 ptr == address 检查间歇性失败的原因。在受影响的 AIX jobs 上测试不再崩溃即表示完成。
