There was a problem hiding this comment.
I am wondering if it is more technically correct to put these in cflags_cc but based on other existing usages in the same gyp file and that it has been tested to work LGTM.

When building node.js with
--sharedon AIX thetorqueexecution consistently fails with a segmentation fault. This has been tracked down by a change in the v20 timeframe when V8 was updated to 11.3.244.4 but at an initial cursory glance it's not immediately clear which change caused it.By experimentation (by other teams I have spoken to and extra work by myself) it has also been observed that dropping the optimisation level from
-O3to-O1on one source file reliably prevents the crash from occurring. Just to be clear, this problem does not occur on the non-shared library build therefore this change reduces the optimisation only for the shared build and only on AIX.It is hoped that with this change we can reactivate the node-test-commit-aix-shared-lib job and maybe even add in the additional testing being proposed under #61463 in the future.
