Description Faustus 2010-11-04 19:19:54 UTC

/usr/bin/jsc segfaults on hardened x86 (strace: mmap2 with PROT_EXEC)

paxctl -m /usr/bin/jsc fixes the issue

I wonder if the underlying problem with Javascript in WebKit calling mmap with PROT_EXEC can be fixed somehow, and then neither jsc nor, probably, midori, will need to have their memory protection disabled (see bug 338561).

Can we add a use flag to disable jit or wait for it to get fixed upstream?
