* g10/getkey.c (get_user_id): Do not call xmalloc with 0. * common/xmalloc.c (xmalloc, xcalloc): Take extra precaution not to pass 0 to the arguments. -- The problem did not occur in 1.x because over there the xmalloc makes sure to allocate at least one byte. With 2.x for most calls the xmalloc of Libgcrypt is used and Libgcrypt returns an error insteead of silent allocating a byte. Thus gpg 2.x bailed out with an "Fatal: out of core while allocating 0 bytes". The extra code in xmalloc.c is for more robustness for the other xmalloc calls. (cherry picked from commit 99972bd6e9abea71f270284f49997de5f00208af) Resolved conflicts: g10/getkey.c - ignore whitespace changes.
JNLIB - This is a collection of utility function which are too small to put into a library. The code here is licensed under the LGPL. libjnlib-config.h should be be modified for each project to make these functions fit into the software. Mainly these are memory functions in case you need another allocator.
