qgrep only returns one result for "media-libs/libsdl2". strace reveals that it is not closing each file each use so it quickly runs out of file descriptors. Here's the point in the strace output where that happens. openat(1021, "app-crypt/easy-rsa/easy-rsa-3.0.5.ebuild", O_RDONLY|O_CLOEXEC) = 1022 openat(4, "../..", O_RDONLY|O_CLOEXEC) = 1022 openat(1022, "app-crypt/keylookup/keylookup-2.2.ebuild", O_RDONLY|O_CLOEXEC) = 1023 openat(4, "../..", O_RDONLY|O_CLOEXEC) = 1023 openat(1023, "app-crypt/hashcat/hashcat-5.0.0.ebuild", O_RDONLY|O_CLOEXEC) = -1 EMFILE (Too many open files) openat(4, "../..", O_RDONLY|O_CLOEXEC) = -1 EMFILE (Too many open files) openat(AT_FDCWD, "app-crypt/ccrypt/ccrypt-1.11.ebuild", O_RDONLY) = -1 EMFILE (Too many open files) openat(4, "../..", O_RDONLY|O_CLOEXEC) = -1 EMFILE (Too many open files) openat(AT_FDCWD, "app-crypt/certbot-nginx/certbot-nginx-0.33.1.ebuild", O_RDONLY) = -1 EMFILE (Too many open files) openat(4, "../..", O_RDONLY|O_CLOEXEC) = -1 EMFILE (Too many open files)
oh yeah! it leaks, Linux is way more restrictive than Solaris, which is why I could grep an entire tree and not notice ... oops
