Package: sympow Version: 1.023-8 Severity: important Dear Maintainer,
sympow now segfaults with basic input, possibly due to libc upgrades - I didn't see these before when we were testing with Sage 7.4. The failure is definitely independent of Sage: $ gdb -q sympow Reading symbols from sympow...Reading symbols from /usr/lib/debug/.build-id/4a/af4652689eadb85484e33a562f7ff64ecc20d9.debug...done. done.
