Subject: [PATCH 12/12] src: Record and print global exception backtraces
|
|
|
|
We have a central place to catch global exceptions. Unfortunately the
|
|
act of doing that hides the exception if OCAMLRUNPARAM=b was set.
|
|
|
|
We almost always want to see where these exceptions are thrown so turn
|
|
on exception recording unconditionally and print them.
