> GC_ADD_CALLER is used in case of absence of GC_CAN_SAVE_CALL_STACKS. The latter macro is defined on Linux but not on FreeBSD, and GC_RETURN_ADDR_PARENT and GC_caller_func_offset are used (as the only alternative to missing support of GC_CAN_SAVE_CALL_STACKS) to record the caller of GC_debug_malloc/realloc_replacement. Unfortunately, __builtin_return_address(1) is not supported on all H/W (e.g., ARM or MIPS), so I currently enabled it for x86/x64.

Yup, seems to work fine for me. Note that I only have FreeBSD on amd64,
so I can't test changes related to ARM, SPARC or MIPS platforms.
Also, could you add the test for 'enable_parallel_mark' into the
'*-*-freebsd*)' part of the 'case $host' in configure.ac? It's there in
7_3 branch, but not in the 7_2 or 'freebsd-ports-devel-boehm-gc'. Note
that '*-*-kfreebsd*-gnu)' has that test for both 7_3 and 7_2 branches.
