Subject: Fix: Added a null pointer check to bt_ctf_field_name
X-Git-Tag: v1.1.0~24
X-Git-Url: http://git.efficios.com/?p=babeltrace.git;a=commitdiff_plain;h=217b52c547ffee31e342cc5c3c1a1f6c6de2d3cf

Fix: Added a null pointer check to bt_ctf_field_name

This function is called indirectly when calling __repr__ (print) in the
python bindings on the definition object returned by the
get_top_level_scope method thus resulting in a segmentation fault when
the name attribute is not set.

Fixes #373
