I’ve updated my backtrace patch to work with OCaml 3.11.x as well as 3.10.x. The patch provides
-
access to backtraces from within a program (this is already provided in stock 3.11.x)
-
backtraces for dynamically-loaded bytecode
-
backtraces in the (bytecode) toplevel
In addition there are a few improvements since the last version:
-
debugging events are allocated outside the heap, so memory use should be better with forking (on Linux at least, the data is shared on copy-on-write pages but the first GC causes the pages be copied)
-
fixed a bug that could cause spurious “unknown location” lines in the backtrace
-
a script to apply the patch (instead of the previous multi-step manual process)
See ocaml-backtrace-patch on Github or download the tarball.
