Android's Bionic libc stores the thread ID in TLS slot 1 instead of 0 on 32-bit ARM and AArch64. Slot 0 contains a pointer to the ELF DTV (Dynamic Thread Vector) instead, which is constant for each loaded DSO. Because mimalloc uses the thread ID to determine whether operations are thread-local or cross-thread (atomic), all threads having the same ID causes internal data structures to get corrupted quickly when multiple threads are using the allocator: mimalloc: assertion failed: at "external/mimalloc/src/page.c":563, mi_page_extend_free assertion: "page->local_free == NULL" mimalloc: assertion failed: at "external/mimalloc/src/page.c":74, mi_page_is_valid_init assertion: "page->used <= page->capacity" mimalloc: assertion failed: at "external/mimalloc/src/page.c":100, mi_page_is_valid_init assertion: "page->used + free_count == page->capacity" mimalloc: assertion failed: at "external/mimalloc/src/page.c":74, mi_page_is_valid_init assertion: "page->used <= page->capacity" Add support for Android's alternate TLS layout to fix the crashes in multi-threaded use cases. Fixes #376. |
