$ echo '+:::::
+:::::' | uniq -u
uniq: string comparison failed: No such file or directory
uniq: Set LC_ALL='C' to work around the problem.
uniq: The strings compared were `+:::::' and `+:::::'.
The whole error checking in memcoll and xmemcoll is completely bogus. The
C standard says in 7.5#3:
The value of errno may be set to nonzero by a library function call
whether or not there is an error, provided the use of errno is not
documented in the description of the function in this International
Standard.
In section 7.21 (String handling <string.h>) the word errno is mentioned
exactly once, in the description of strerror. None of the other string
functions are obliged to care about errno in any way.
