Thanks!  I was wondering if the error message was:
  (a) due to a problem dynamically linking libgccjit into the process, or
  (b) a later problem with linking the code that libgccjit generates into t=
he
process.

Given that there's no extra log output at all with the protection flag, it
sounds like it's (a) - though you may run into a similar problem with (b)
if/when (a) gets solved.=
