This feature is guarded by BOOST_STACKTRACE_ALWAYS_STORE_IN_PADDING, but that is only enabled on x86 ( https://github.com/boostorg/stacktrace/blob/a33e198cf660c213e700d6f050a4641b...). This means that ./bootstrap.sh --with-toolset=gcc --with-libraries=stacktrace ./b2 install threading=multi toolset=gcc always fails to build on non-x86 platforms. There are three current workarounds: 1) set boost.stacktrace.from_exception=off 2) set BOOST_STACKTRACE_LIBCXX_RUNTIME_MAY_CAUSE_MEMORY_LEAK 3) build with threading=single (1) prevents me from using this feature. (2) shouldn't be needed on it's face because I'm using gcc/libstdc++. (3) affects more than stacktrace. Is this an incidental error, or is there a reason I wasn't able to deduce as to why this feature can't be used on non-x86+libstdc++? It seems like the check for libc++ on non-x86 can't be entirely done at compile time. I definitely understand wanting to alert users to the dangers of using this feature, but there also doesn't seem to be a good way of detecting the presence of libc++ at compile time (hence the need for https://github.com/boostorg/stacktrace/blob/a33e198cf660c213e700d6f050a4641b... ). Thanks. - Tim
