New issue 342 by chefm...@gmail.com: Segfault in instrumented programs that
use GNU indirect functions.
https://code.google.com/p/address-sanitizer/issues/detail?id=342
What steps will reproduce the problem?
1. Testcase is attached. Compile with GCC with -fsanitize=address option.
2. Run.
3.
What is the expected output? What do you see instead?
Expected:
Got: Segmentation fault (core dumped).
What version of the product are you using? On what operating system?
Compiler: gcc version 5.0.0 20140916 (experimental) (GCC).
OS: Linux 3.2.0-56-generic #86-Ubuntu 12.04 x86_64 x86_64 x86_64 GNU/Linux
Please provide any additional information below.
It seems that resolution of indirect function's implementation happens
before asan_init invokes, so if ASan inserts red zones into resolver's
stack, we will have segfault.
