--- Begin Message ---Package: libc6 Version: 2.5-6 Severity: normal Hi, there happens a segmentation fault with the following code: #include <stdio.h> int main(int argc, char**argv) { printf("%s\n", strerror(atoi(argv[1]))); } I have observed this on amd64 libc6 2.5-5 and 2.5-6, it does not occur on i386 libc6 2.5-5. The amd64 system is actually an amd64 schroot running on a sarge/i386 host. If there is anything I can do to help you debug this, please let me know. A small test log is appended below.
