Description

This is only for libasan support:

20777 prctl(PR_GET_DUMPABLE)            = 157
20777 --- SIGSYS {si_signo=SIGSYS, si_code=SYS_SECCOMP, si_call_addr=0x7f552ac9f047, si_syscall=__NR_prctl, si_arch=AUDIT_ARCH_X86_64} ---

We would need to support PR_GET_DUMPABLE.

Since the sandbox didn't support asan before, let's call this a new feature for 0.3.3?

Yes libasan specific... We could also just call it "not supported with libasan" and be done with this ticket? :)

These tickets, tagged with 034-removed-*, are no longer in-scope for 0.3.4. We can reconsider any of them, if time permits.
