[package] boost/1.85.0: GCC on macOS fails to compile from_exception.cpp

[randomphrase]

Description

Building boost 1.85.0 on macOS with GCC, we get a compilation error as follows:

libs/stacktrace/build/../src/from_exception.cpp:29:2: error: #error On this platform memory leaks are possible if capturing stacktrace from exceptions is enabled and exceptions are thrown concurrently and libc++ runtime is used. Define `BOOST_STACKTRACE_LIBCXX_RUNTIME_MAY_CAUSE_MEMORY_LEAK` to suppress this error if the library would not be used with libc++ runtime (for example, it would be only used with GCC runtime). Otherwise, disable the boost_stacktrace_from_exception library build (for example by `./b2 boost.stacktrace.from_exception=off` option).
   29 | #error On this platform memory leaks are possible if capturing stacktrace from \
      |  ^~~~~
...failed updating 1 target...

Note that the Conan recipe will define this symbol, according to the following logic in the recipe:

if self._stacktrace_from_exception_available and is_apple_os(self) and str(self.settings.compiler.libcxx) == "libc++":

To me this seems backwards: the memory leak exists only in the libc++ runtime, hence if anything we should define the symbol (and hence allow compilation) only if we are not using that runtime. As it stands we can only compile against the problematic runtime.

libs/stacktrace/build/../src/from_exception.cpp:29:2: error: #error On this platform memory leaks are possible if capturing stacktrace from exceptions is enabled and exceptions are thrown concurrently and libc++ runtime is used. Define `BOOST_STACKTRACE_LIBCXX_RUNTIME_MAY_CAUSE_MEMORY_LEAK` to suppress this error if the library would not be used with libc++ runtime (for example, it would be only used with GCC runtime). Otherwise, disable the boost_stacktrace_from_exception library build (for example by `./b2 boost.stacktrace.from_exception=off` option).

It may be related to boostorg/stacktrace#163

I'll send a hotfix to always set BOOST_STACKTRACE_LIBCXX_RUNTIME_MAY_CAUSE_MEMORY_LEAK

Users still can disable stacktrace.from_exception
