I use tb-13 day in and day out on hardened without a bit of > trouble. Yeah, I see it now. If you look at the next lines after the mmap you see that's its trying to set up jit for javascript: mmap(NULL, 65536, PROT_READ|PROT_WRITE|PROT_EXEC, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x6f9d50028000 access("/home/steven/.thunderbird/c9tpzjz8.default/prefs.js", F_OK) = 0 open("/home/steven/.thunderbird/c9tpzjz8.default/prefs.js", O_RDONLY) = 17 Close invalid since we have -jit on the hardened profiles?
OK i've removed the JIT USE flag and reemerged all affected packages (PCRE, Firefox, Thunderbird). Thunderbird starts now without any issue. Thank you for pointing me to the root cause.
- setting the status of the bug to resolved-invalid as the root cause was the wrong used USE flag "jit"
Please leave open as I have intended for this to work both ways. I will continue to work on a proper fix to support +jit as well.
reopen if bug comes back.
