[Bug libc/10246] New: glob() with GLOB_NOCHECK is returning a modified pattern sometimes

[psmith at gnu dot org]

Actually I see this with glibc 2.7-13 but there's no 2.7 in the version list?

According to POSIX, glob() with GLOB_NOCHECK should:

> If pattern does not match any pathname, then glob() shall return a list
> consisting of only pattern, and the number of matched pathnames is 1.

However, if I invoke glob() with a pattern of "//<word>" where <word> is any
non-slash-containing string that I've tried, then the resulting string is
"/<word>" with the initial slash removed.

If there are more than two initial slashes, it works fine.  Likewise if there
are extra directory levels in the pattern.

I will attach a test program I wrote:

$ gcc -o /tmp/gtest /tmp/gtest.c

$ /tmp/gtest /%
0: /bin

$ /tmp/gtest //%
0: /bin     <--incorrect!

$ /tmp/gtest ///%
0: ///%     <--OK

$/tmp/gtest //a/b
0: //a/b    <--OK
