libstdc++: Make std::filesystem::copy_file work for procfs [PR108178]
The size reported by stat is always zero for some special files such as
those under /proc, which means the current copy_file implementation
thinks there is nothing to copy. Instead of trusting the stat value, try
to read a character from a streambuf and check for EOF.
libstdc++-v3/ChangeLog:
PR libstdc++/108178
* src/filesystem/ops-common.h (do_copy_file): Check for empty
files by trying to read a character.
* testsuite/27_io/filesystem/operations/copy_file_108178.cc:
New test.
