I'm trying to bump media-gfx/asymptote to 3.00. This version bundles a modified source of dev-libs/boehm-gc-8.2.8. When building asymptote-3.00/gc I get sandbox violations like F: open_wr S: deny P: /proc/4643/clear_refs A: /proc/4643/clear_refs R: /proc/4643/clear_refs C: ./cordtest for the programs cordtest, gctest, staticrootstest, disclaim_test, disclaim_weakmap_test. I can successfully run these test programs by hand, and, indeed, they write to /proc/<pid>/clear_refs: # strace -e trace=file ./cordtest ... openat(AT_FDCWD, "/proc/3702/clear_refs", O_WRONLY) = 3 ... +++ exited with 0 +++ It is absolutely legal for the owner of a process to write to /proc/<pid>/clear_refs. Why does sandbox forbids it? I've tried to add addwrite /proc at the beginning of src_compile. Result: all these tests programs run without sandbox errors, and after that the build hangs. No messages, the load level 0, emerge is running forever. So, this simple solution does not work.
So there seems to be two separate issues here: 1. You want to allow write access to /proc/PID/clear_refs by default. 2. Even when write access is allowed, something is hanging your process. For the second issue, does it work with FEATURES="-usersandbox -sandbox"?

Yes. emerge succeeds, the resulting asymptote works. With USE=doc, the manual is successfully generated (this process includes running >80 asy scripts, many of them are highly non-trivial)
Ok, please file a separate bug for the hanging process issue and include more details.
Running these boehm-gc test programs is absolutely unnecessary for building asymptote. I've patched it out of the relevant Makefile.in. So, my immediate problem is solved.
