Thanks for reporting this. I can confirm the bug. It is triggered by the
upgrade of libpcre3, from version 1:8.31-5 to 1:8.35-2. Downgrading to
libpcre3 1:8.31-5 solves the issue.

At this stage, I don't know if this is an ABI break in libpcre3 (#755439
looks like a possible candidate), or if it is related to the way Julia
internally stores regular expressions in its LLVM bytecode image
(sys.ji).
