Hi all,

I am getting segfaults when executing gpg --gen-key (and other
operations like --sign)

my system is running linux kernel 2.6.16.x, gcc 4.1.1 and glibc 2.3.6.

seems like it segfaults when calling tty_printf, can you help?


Here is the backtrace

(gdb) run --gen-key
Starting program: /mnt/hdb/ying/gnupg-1.4.6/g10/gpg --gen-key
