This was done by +making the mmb_heap_lock into a recursive lock and making the +regular heap_lock extend to cover the mmb heap handling. + +Also move the new_mmb allocation up to before the mmb list is +iterated through to find the insertion point. When the mmb_heap +also runs out and needs to be extended when the regular heap is +just extended, the mmb list could be messed up. + +Signed-off-by: Freeman Wang <xwang@ubicom.com> +Signed-off-by: Austin Foxley <austinf@cetoncorp.com> +--- + libc/stdlib/malloc/free.c | 6 +++--- + libc/stdlib/malloc/malloc.c | 7 ++++--- + 2 files changed, 7 insertions(+), 6 deletions(-) + +diff --git a/libc/stdlib/malloc/free.c b/libc/stdlib/malloc/free.c +index 90e18f4..741248a 100644 +--- a/libc/stdlib/malloc/free.c ++++ b/libc/stdlib/malloc/free.c +@@ -179,14 +179,14 @@ __free_to_heap (void *mem, struct heap_free_area **heap + /* Start searching again from the end of this block. */ + start = mmb_end;
