This is indeed partially a glibc bug, already reported upstream there: https://sourceware.org/bugzilla/show_bug.cgi?id=27476 Note however that the feature of calling getcwd(NULL, >0) is a GNU extension, and that the above code doesn't define _GNU_SOURCE, so this is also a bug in the package. Please also note that there are discussion to deprecate the support of size > 0 when buf is NULL: https://sourceware.org/bugzilla/show_bug.cgi?id=26545 -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurel...@aurel32.net http://www.aurel32.net
