+Subject: [PATCH] Fix SIGSEGV in remove_all_threads_but_me if fork from
+ unregistered thread (a cherry-pick of commit 44fbb3b9e from 'master')
+
+Issue #783 (bdwgc).
+
+Some clients call `fork()` from an unregistered thread, thus we might
+find no entry for the current thread in `GC_remove_all_threads_but_me`.
+
+* include/gc.h (GC_atfork_child): Add comment about `fork()` from
+an unregistered thread.
+* pthread_support.c [CAN_HANDLE_FORK] (GC_remove_all_threads_but_me):
+If `me` is null, then return immediately after loop (instead of `ABORT`
+or the assertion, regardless of `CPPCHECK` and `LINT2`).
+* win32_threads.c [CAN_HANDLE_FORK] (GC_remove_all_threads_but_me):
+Likewise.

+Subject: [PATCH] Fix SIGSEGV if pthread_detach is called before collector
+ initialization (a cherry-pick of commit e40697e26 from 'master')
+
+The only case this seems to be needed is when the client calls
+`pthread_detach(pthread_self())` before the collector initialization.
+
+* pthread_support.c [!SN_TARGET_ORBIS && !SN_TARGET_PSP2]
+(GC_pthread_detach): Call `GC_init()` if the collector is not
+initialized; add comment.
+* win32_threads.c [GC_PTHREADS] (GC_pthread_detach): Likewise.
