The Open MPI code base assumed that asprintf always behaved like the FreeBSD variant, where ptr is set to NULL on error. However, the C standard (and Linux) only guarantee that the return code will be -1 on error and leave ptr undefined. Rather than fix all the usage in the code, we use opal_asprintf() wrapper instead, which guarantees the BSD-like behavior of ptr always being set to NULL. In addition to being correct, this will fix many, many warnings in the Open MPI code base. Signed-off-by: Brian Barrett <bbarrett@amazon.com>
