Hi All,

When I compile with GCC and Debug config (only Debug), process stops with these errors:

Changing config to anything than Debug solves the issue, but along the way there are some warnings, of which these three seems to be particularly important:

tests_reg/build_spe/build-spe/lib/ext/mbedcrypto-src/include/mbedtls/ecp.h:365: warning: "MBEDTLS_ECP_MAX_BYTES" redefined

  132 | #warning "Use legacy driver API for BL2"

When I try to compile with Clang compiler latest version 6.21, I immediately get this error:
