Bug ID: 31861
Summary: address sanitizer and jni does not work
Product: clang
Version: 3.9
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: Static Analyzer
Assignee: kremenek at apple.com

Source code and make.sh
I utilize the address sanitizer to detect errors in shared libraries. When I
try to interface a shared library with java via jni the address
sanitizer it does no longer work. This has been working with gcc versions 5, 6
and
earlier versions of gcc 7.
For previous version of gcc setting DYLD_INSERT_LIBRARIES is not necessary.
Setting DYLD_INSERT_LIBRARIES as suggested for current versions of gcc 7 on
the x86_64-apple-darwin15.6.0 target does not solve the issue.
I do not know how to successfully preload libasan on darwin. It does
not seem to work for the version of clang shipped with the operating system
(Apple LLVM version 8.0.0 (clang-800.0.42.1)) or with clang 3.9.0, either:
Therefore,
Maxim Ostapenko asked me to submit a bug report in the LLVM bug tracker:
(See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79096)
|Could you please raise a bug in LLVM bug tracker (https://llvm.org/bugs/)? All
|changes to sanitizer runtime library should go to LLVM and after they fix this
|bug we can backport corresponding patch to GCC.
