SUMMARY: AddressSanitizer: 26240 byte(s) leaked in 143 allocation(s).

Steps to reproduce:

0. Start the 'debian-buster' image and run the following instructions in it:

   docker run --network=host -v $PWD:/source -w /source -ti registry.gitlab.com/tarantool/tarantool/testing/debian-buster

1. Build with ASAN:

   make -f .travis.mk test_asan_debian

2. Block suppression at LSAN table list:

   diff --git a/asan/lsan.supp b/asan/lsan.supp
   index 3273c3baf..224e88019 100644
   --- a/asan/lsan.supp
   +++ b/asan/lsan.supp
   @@ -38,7 +38,7 @@ leak:AccessDeniedError::AccessDeniedError
   
   # test: box/bitset.test.lua
   # source: src/lib/bitset/iterator.c
   -leak:tt_bitset_iterator_init
   +#leak:tt_bitset_iterator_init
   
   # test: box-py/args.test.py
   # source: /lib/x86_64-linux-gnu/libc.so*

3. Create reproducer 'box/bitset_gh-5188.test.lua' in 'test' directory:

   -- value '50' can be changed to '5' to avoid of issue and to '500' to get the issue more frequently
   s = box.schema.space.create('test')
   _ = s:create_index('primary', { type = 'hash', parts = {1, 'unsigned'}, unique = true })
   i = s:create_index('bitset', { type = 'bitset', parts = {2, 'unsigned'}, unique = false })
   for n = 1, 50, 1 do \
   i:pairs(7, {iterator = box.index.BITS_ANY_SET}) \
   end
   s:drop()
   s = nil

4. Update result for the new test file:

   cd test
   export ASAN_OPTIONS=heap_profile=0:unmap_shadow_on_exit=1:detect_invalid_pointer_pairs=1:symbolize=1:detect_leaks=1:dump_instruction_bytes=1:print_suppressions=0:verbosity=9 ; export LSAN_OPTIONS=suppressions=/source/asan/lsan.supp ; ./test-run.py box/bitset_gh-5188.test.lua --update-result

5. Run a few times till the issue appears:

   export ASAN_OPTIONS=heap_profile=0:unmap_shadow_on_exit=1:detect_invalid_pointer_pairs=1:symbolize=1:detect_leaks=1:dump_instruction_bytes=1:print_suppressions=0:verbosity=9 ; export LSAN_OPTIONS=suppressions=/source/asan/lsan.supp ; ./test-run.py --force box/bitset_gh-5188.test.lua

6. Check the log:

   less var/001_box/box.log

7. Found that function 'src/lib/bitset/iterator.c:tt_bitset_iterator_init' used 49 times, when LSAN showed the issue, and 50 times when didn't, also didn't use 'src/lib/bitset/iterator.c:tt_bitset_iterator_destroy' in both variants.
8. Found that 'count' instead of 'pairs' didn't show any memory leaks, also src/lib/bitset/iterator.c:tt_bitset_iterator_destroy used the same as 'src/lib/bitset/iterator.c:tt_bitset_iterator_init' 50 times.

Optional (but very desirable):

• coredump
• backtrace
• netstat

@avtikhon, I glanced the issue description and strongly doubt this one relates to LuaJIT, since I see no LuaJIT routines in backtraces reported by sanitizer. The problem might relate to some Lua code in Tarantool, but I still suggest replacing luajit label with the corresponding one.

[Totktonada]

@avtikhon If you'll create a docker/test-run free reproducer, I guess it will be enough to file an issue against the development team.
