However, two updates from my testing last night.
1) The twig testsuite is run using phpunit. phpunit has a parameter --process-isolation. When the
tests are run with that parameter, the tests pass (even with pcre.jit left on). This, I think,
points to a PHP bug, but I'm not sure.
2) When I tried to just run the failing twig tests on their own (split_utf8.test and
length_utf8.test are the two input files), I could not recreate the segmentation fault. This again,
it feels like, points to a fault somewhere in the php logic due to some corrupt state, perhaps?

One of the JIT bugs in pcre. It should be reported upstream.

Adding pcre.jit=0 to the invocation of the tests (-d parameter to phpunit) allows the test to
succeed.

I apologize, but I'm not a PHP developer. The twig testsuite is publicly available from github.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.
