Bug fixes:

  • #8855, #8858: Links for tools not created when installing with --disable-installing-byecode-programs (e.g. ocamldep.opt installed, but ocamldep link not created) (David Allsopp, report by Thomas Leonard)

  • #8947, #9134, #9302: fix/improve support for the BFD library (Sébastien Hinderer, review by Damien Doligez and David Allsopp)

  • #8953, #8954: Fix error submessages in the toplevel: do not display dummy locations (Armaël Guéneau, review by Gabriel Scherer)

  • #8965, #8979: Alpine build failure caused by check-parser-uptodate-or-warn.sh (Gabriel Scherer and David Allsopp, report by Anton Kochkov)

  • #8985, #8986: fix generation of the primitives when the locale collation is incompatible with C. (David Allsopp, review by Nicolás Ojeda Bär, report by Sebastian Rasmussen)

  • #9050, #9076: install missing compilerlibs/ocamlmiddleend archives (Gabriel Scherer, review by Florian Angeletti, report by Olaf Hering)

  • #9073, #9120: fix incorrect GC ratio multiplier when allocating custom blocks with caml_alloc_custom_mem in runtime/custom.c (Markus Mottl, review by Gabriel Scherer and Damien Doligez)

  • #9144, #9180: multiple definitions of global variables in the C runtime, causing problems with GCC 10.0 and possibly with other C compilers (Xavier Leroy, report by Jürgen Reuter, review by Mark Shinwell)

  • #9180: pass -fno-common option to C compiler when available, so as to detect problematic multiple definitions of global variables in the C runtime (Xavier Leroy, review by Mark Shinwell)

  • #9128: Fix a bug in bytecode mode which could lead to a segmentation fault. The bug was caused by the fact that the atom table shared a page with some bytecode.
