==9054==WARNING: AddressSanitizer failed to allocate 0x002bffffffd4 bytes

HI!
When I run ASAN with a target program, the log shows that
==9054==WARNING: AddressSanitizer failed to allocate 0x002bffffffd4 bytes ==9054==AddressSanitizer's allocator is terminating the process instead of returning 0 ==9054==If you don't like this behavior set allocator_may_return_null=1 ==9054==AddressSanitizer CHECK failed: ../../../../src/libsanitizer/sanitizer_common/sanitizer_allocator.cc:147 "((0)) != (0)" (0x0, 0x0) #0 0x7ff2c4e6a631 (/usr/lib/x86_64-linux-gnu/libasan.so.2+0xa0631) #1 0x7ff2c4e6f5e3 in __sanitizer::CheckFailed(char const*, int, char const*, unsigned long long, unsigned long long) (/usr/lib/x86_64-linux-gnu/libasan.so.2+0xa55e3) #2 0x7ff2c4de7425 (/usr/lib/x86_64-linux-gnu/libasan.so.2+0x1d425) #3 0x7ff2c4e6d865 (/usr/lib/x86_64-linux-gnu/libasan.so.2+0xa3865) #4 0x7ff2c4decb4d (/usr/lib/x86_64-linux-gnu/libasan.so.2+0x22b4d) #5 0x7ff2c4e625d2 in malloc (/usr/lib/x86_64-linux-gnu/libasan.so.2+0x985d2) #6 0x443820 in operator new[](unsigned long) (/home/cx/workspace/target_group/sam2p/sam2p+0x443820) #7 0x45153b (/home/cx/workspace/target_group/sam2p/sam2p+0x45153b) #8 0x452495 (/home/cx/workspace/target_group/sam2p/sam2p+0x452495) #9 0x549071 (/home/cx/workspace/target_group/sam2p/sam2p+0x549071) #10 0x405584 (/home/cx/workspace/target_group/sam2p/sam2p+0x405584) #11 0x403259 (/home/cx/workspace/target_group/sam2p/sam2p+0x403259) #12 0x7ff2c4a2082f in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x2082f) #13 0x4048d8 (/home/cx/workspace/target_group/sam2p/sam2p+0x4048d8)
How to solve this problem?
