            Bug ID: 83425
           Summary: No warning about assignment int to unsigned
           Product: gcc
           Version: 7.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: Hi-Angel at yandex dot ru
  Target Milestone: ---

Steps to reproduce:

        $ cat test.cpp
        int ret_int() { return -1; }

        int main() {
                unsigned foo = ret_int();
                (void)foo; // suppress unused variable warning
        }
        $ g++ test.cpp -o a -Wall -Wextra -Wpedantic
        $

It does have a real-world significance, I actually found it because the like
mistake introduced a bug for me, code like:

        [snip]
        uint bytes = purple_ssl_read(ssl, &buf[0], toread);
        if (bytes <= 0) {
        [snip]
