some problem about pcl and eigen

My code,Test3Dto3Dmatch.cpp, runs successfully when compiled in Debug mode. However, when I compile it in Release mode, I encounter a heap-buffer-overflow issue. To debug this, I added "-fno-omit-frame-pointer" and "-fsanitize=address" to the CMakeLists file. The error seems to occur within the Eigen library at Eigen::internal::handmade_aligned_free(void)*. I suspect the issue may be within functions like bimToslam::ISSextractor::operator() and bimToslam::Frontend::ExtractandMatchISS(), which are used for point cloud feature extraction. To investigate further, I created a new test file, TestISSextractor.cpp, and removed the parts related to Eigen. However, I still encounter the same error, roughly as follows:

==21835==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x7fffd3e607f8 at pc 0x5555555e6f82 bp 0x7fffda9fd3e0 sp 0x7fffda9fd3d0 READ of size 8 at 0x7fffd3e607f8 thread T1 ... 0x7fffd3e607f8 is located 8 bytes to the left of 15672944-byte region [0x7fffd3e60800,0x7fffd4d52e70) allocated by thread T1 here: #0 0x7ffff6ef6b40 in __interceptor_malloc (/usr/lib/x86_64-linux-gnu/libasan.so.4+0xdeb40) #1 0x7ffff602fa88 in Eigen::internal::aligned_malloc(unsigned long) (/usr/lib/x86_64-linux-gnu/libpcl_filters.so.1.8+0x311a88)

I tried searching online and found similar issues, suggesting a problem between PCL and Eigen libraries. Some solutions involve enabling AVX instruction sets, so I added "-mavx2" in the CMakeLists file, but the issue remains unresolved. Here is my codehttps://github.com/timetosaygoodb/bimToslam.Here is the reference #4859

Reproduce the Release-only AddressSanitizer failure using Test3Dto3Dmatch.cpp and the isolated TestISSextractor.cpp, reviewing the CMakeLists sanitizer and AVX2 flags. Trace the reported allocation through bimToslam::ISSextractor::operator() and bimToslam::Frontend::ExtractandMatchISS(), and compare the findings with reference issue #4859. Done means the PCL issue is isolated to a reproducible cause and a verified fix or clear diagnosis is documented.
