clang++ - Clangs SanitizerCoverage with shared libraries -


i having trouble in using sancovtool of clang shared libraries.
while works documented simple binary not able work shared libraries.

whenever use shared library program *.sancov file when try report sancov receive following error message:

ignoring libmylib.so , coverage because __sanitizer_cov* functions not found.

it seems problem stems fact the sanitizer functions unresolved in shared library. not sure though.

nm libmylib.so | grep saniti
u __sanitizer_cov
u __sanitizer_cov_module_init
u __sanitizer_cov_with_check

can give me hint doing wrong?

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
