The new malloc from Doug Lea caught a bug in
man, version 2.3.10, db 2.3.1, July 12th, 1995 (G.Wilford@ee.surrey.ac.uk)
The setlocale man page under Linux doesn't say the string returned by
setlocale () will be overwritten by a subsequent call to setlocale(),
which is mentioned in the SunOS version.
BTW, libc 5.3.0 looks pretty good. If you find your program doesn't
work anymore with 5.3.0, please debug your program first. man
is the second bogus libc 5.3.0 report I got.
