** Description changed:
[Impact]
Binaries built w/ asan support hang on arm64. This causes many timeouts
during the test phase of a gcc build, causing builds to need ~24 hours to
complete.
[Test Case]
$ cat test.c
#include <stdio.h>
void main() {
- printf("hi.\n");
+ printf("hi.\n");
}
$ gcc test.c -g -fsanitize=address -fno-omit-frame-pointer test.c -o test
$ ./test
==46644==AddressSanitizer CHECK failed:
../../../../src/libsanitizer/sanitizer_common/sanitizer_allocator.h:844
"((res)) < ((kNumPossibleRegions))" (0xffffb4b, 0x8000000)
[... HANG ...]
+ Plus see the tests in the libasan testsuite succeed.
+
[Regression Risk]
+ None, unless the 48bit-vma support is removed again from the kernel. Can't
find the corresponding kernel SRU which explained the regression potential in
this kernel change.
