On a PaX-enabled system, when I was trying to upgrade to 15.11.0 years ago, I noticed the pax_kernel flag was broken and caused build failure due to incomplete PaX marking. After troubleshooting, the required markings were: out/Release/mksnapshot_u m out/Release/mkcodecache_u m out/Release/node_mksnapshot_u m out/Release/genccode m Today I was attempting to upgrade to net-libs/nodejs-18.11.0 (now with pax-kernel instead of pax_kernel flag), and I noticed the same problem still exists. Thus, the "pax-kernel" flag in almost all currently available nodejs ebuilds are broken.
Mysteriously, this problem went away after another attempt to reinstall net-libs/nodejs-18.11.0 for reproducing the problem... Perhaps my system's paxmark.sh was simply broken? Apologize for the noise. Close as INVALID.
