Failed assertion w/ASan on Linux and clang #1801
Description
Summary
This is the same issue reported in #1726 that was fixed for GCC by in #1782, but still reproduces for clang and derivatives:
$ /build/clang_18.1_cxx11_64_debug/test_task
[doctest] doctest version is "2.4.11"
[doctest] run with "--help" for options
Assertion &stack_limit > stack_limit failed (located in the get_stack_attributes function, line in file: 177)
Detailed description: stack size must be positive
===============================================================================
test/tbb/test_task.cpp:124:
TEST CASE: External threads sleep
test/tbb/test_task.cpp:124: FATAL ERROR: test case CRASHED: SIGABRT - Abort (abnormal termination) signal

Aborted
Right now the stack size calculation via Posix calls (triggering the assertion on the ASan fake stack) is excluded by:
Line 172 in 8652376
Unfortunately, the way to detect ASan changes across toolchains:
- clang uses
__has_feature, doesn't define__SANITIZE_ADDRESS__(see here) - GCC defines
__SANITIZE_ADDRESS__, doesn't support__has_feature(see here and here)
The behaviour of the __SANITIZE_ADDRESS__ macro across toolchains is shown here.
