How integer overflow in CsoundMYFLTArray constructor happens in C++ and how to fix it

A critical integer overflow vulnerability was discovered in `Java/cs_glue.cpp` at line 324, where the `CsoundMYFLTArray` constructor multiplied a user-controlled integer `n` by `sizeof(MYFLT)` without checking for overflow before passing the result to `malloc`. An attacker supplying a value near `INT_MAX` could trigger the overflow, causing an undersized heap allocation that subsequent writes would overflow. The fix adds an explicit `SIZE_MAX / sizeof(MYFLT)` guard and replaces `malloc` with `ca
