Description
Running RcppDeepState with Valgrind and Clang version 14 gives this strange error message:

Premature end of data in tag valgrindoutput line 3 [77]This is the valgrind execution log over the rcpp_read_out_of_bound function of testSAN.

Searching online I found in this thread that the solution for this problem is to force clang to generate source-level debug information with dwarf version 4 using -gdwarf-4 parameter to clang.
