Bug ID: 97414
Summary: AddressSanitizer CHECK failed:
detect_stack_use_after_return and
detect_invalid_pointer_pairs
Product: gcc
Version: 10.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: sanitizer
Assignee: unassigned at gcc dot gnu.org
Reporter: chfast at gmail dot com
CC: dodji at gcc dot gnu.org, dvyukov at gcc dot gnu.org,
jakub at gcc dot gnu.org, kcc at gcc dot gnu.org, marxin at gcc dot gnu.org
Target Milestone: ---
==638106==AddressSanitizer CHECK failed:
../../../../src/libsanitizer/asan/asan_thread.cpp:369 "((bottom)) != (0)" (0x0,

#8 0x55e8cd66410d in _start
(/home/chfast/Projects/compiler_bugs/sanitizers/pointer_subtract_crash/a.out+0x110d)
When running the program
[[gnu::noinline]] auto pointer_diff(const int *begin, const int *end) {
return end - begin;
}
int main() {
constexpr auto size = (2048 / sizeof(int)) + 1;
auto buf = new int[size];
auto end = buf + size;
pointer_diff(end, buf);
delete[] buf;
return 0;
}
compiled with
gcc -fsanitize=address,pointer-subtract -g pointer_subtract_crash.cpp
To reproduce the crash, both runtime options must be enabled:
ASAN_OPTIONS=detect_stack_use_after_return=1:detect_invalid_pointer_pairs=1
This bug was previously reported in LLVM's AddressSanitizer project
https://bugs.llvm.org/show_bug.cgi?id=47626, but pointer-subtract is not
supported there.
