Public bug reported:
[Impact]
libmozjs24 does not support 48-bit virtual addresses on arm64. 48-bit virtual
addresses are enabled in the Ubuntu 16.04 kernel (though not on the kernel used
on the buildds). This causes applications to crash.
[Test Case]
apt source mozjs24
sudo apt build-dep -y mozjs24
sudo apt install -y fakeroot
cd mozjs24-24.2.0
fakeroot make -f debian/rules build
cd js/src
make
./jsapi-tests/jsapi-tests
Unpatched source crashes for me immediately on xenial:
dannf@mustang:~/mozjs24-24.2.0/js/src$ ./jsapi-tests/jsapi-tests
testXDR_sourceMap
Segmentation fault
All tests pass w/ patched source
[Regression Risk]
I'd suggest running through the jsapi-tests on each supported Ubuntu
architecture. I've only ran it on arm64 so far.
