Hello, Right now I am just using a Generator to look for symbols in my process (which links dynamically against libc / libm). It seems to have no trouble finding every other libc / libm / libc++ / ... symbol so I assumed that it was not necessary to specifically link against libm where these __finite symbols reside: $ nm -D /usr/lib/libm.so.6 | grep finite 0000000000050540 T

The DynamicLibrarySearchGenerator is using the getAddressOfSymbol method, which (under the hood) is basically issuing an appropriate dlsym lookup, and that does not find
