Segmentation fault compiling suckless/ubase package

[ghost]

My mail:
Hello Rui
I am Otto.
I have tried your compiler - it looks great!
But I think I found a bug.
I have tried to compile "suckless" project's ubase package
http://git.suckless.org/ubase/
It doesn't compile mount.c - it gives a segfault :(

(libutil/explicit_bzero.c don't compile - gives parse error or internal error)
probably it is not implemented :(

Thank you for your compiler!

it seems the process stops at "defaults" in this struct
struct {
const char *opt;
const char *notopt;
unsigned long v;
} optnames[] = {
{ "defaults", NULL, 0 },
{ "remount", NULL, MS_REMOUNT },
{ "ro", "rw", MS_RDONLY },
{ "sync", "async", MS_SYNCHRONOUS },
{ "dirsync", NULL, MS_DIRSYNC },
{ "nodev", "dev", MS_NODEV },
{ "noatime", "atime", MS_NOATIME },
{ "nodiratime", "diratime", MS_NODIRATIME },
{ "noexec", "exec", MS_NOEXEC },
{ "nosuid", "suid", MS_NOSUID },
{ "mand", "nomand", MS_MANDLOCK },
{ "relatime", "norelatime", MS_RELATIME },
{ "bind", NULL, MS_BIND },
{ NULL, NULL, 0 }
};
