This is a bit weird.
When I compile with -O2 (autoconf default) on OS X 10.5.x, it'll break
because `crypt_get_keys()` will go into the S/MIME part and look for
S/MIME keys even though I use PGP/MIME.
`msg->security` is 259 which means to use PGP (`1 << 8` = 256), `1 << 0` =
1 for encryption and `1 << 1` = 2 for signing (256+1+2=259).
This used to work with -O2. The only thing I changed is upgrading XCode to
3.1.3.
With fink/64bit I use `gcc -arch x86_64`, gcc is:
{{{
gcc version 4.0.1 (Apple Inc. build 5493)
}}}
It does work when I use `gcc-4.2 -arch x86_64` with gcc 4.2:
{{{
gcc version 4.2.1 (Apple Inc. build 5574)
}}}
I can 100% reproduce this. Note that I only need to compile crypt.c using
gcc-4.2 to make it work (here even -O2 is fine).
So this may well be a gcc bug rather than a mutt bug?
