build with -fstack-reuse=none
This will fix the crypto_tests failure on 32-bits platforms.
Backport of core PR15983:
With CMake the flag is set for C++ as well as C, while autotools only
has the C++ flag. This is on purpose as the bug is also affecting gcc
and not only g++. I ran the benchmarks and this caused no noticeable
Fun fact: you can also get rid of the bug by disabling the optimizations
(i.e. build with debug enabled).
cmake -GNinja .. \ -DCMAKE_TOOLCHAIN_FILE=../cmake/platforms/Linux32.cmake \ -DENABLE_STATIC_LIBSTDCXX=ON \ -DENABLE_GLIBC_BACK_COMPAT=ON ninja test_bitcoin ./src/test/test_bitcoin -t crypto_tests
Make sure the test is green. Note that this can't run on WSL because the
kernel only supports 64-bits binaries.
