| Summary: | app-crypt/mit-krb5-1.5.2-r2 segfaults (sample code + /etc/krb5.conf) | ||
|---|---|---|---|
| Product: | Gentoo Linux | Reporter: | Alexandre Bique <bique.alexandre> |
| Component: | [OLD] Library | Assignee: | Gentoo Kerberos Maintainers <kerberos> |
| Status: | VERIFIED WONTFIX | ||
| Severity: | critical | CC: | bique.alexandre |
| Priority: | High | ||
| Version: | unspecified | ||
| Hardware: | x86 | ||
| OS: | Linux | ||
| Whiteboard: | |||
| Package list: | Runtime testing required: | --- | |
AFAIKS this bug has nothing to do with gentoo ... I wan't fix your code ;) If it's library related please contact upstream! (BTW the package is really outdated) |
