[pgrouting-dev] Issue regarding Segmentation Fault: Signal 11

[Sourabh Garg]

Hi all,

I am presently working under GSoC'18, for the project titled "Implementing
Bellman-ford and Parallel Dijkstra for pgrouting". I have
successfully created a function named pgr_bellman_ford which works for one
source to one target parameters inputs[4]. Later, I have transformed the
pgr_bellman_ford function for all variants, by understanding from the
existing pgr_dijkstra function in PR[1], but it is resulting in some
errors[3], which I am not able to figure out. Please review my PR' s
commit[2]. On debugging from Postgres logs trace in src files(.c and .cpp
files), I found that it is giving segmentation fault: signal 11.(see
Attached postgres_log_trace.jpg). Please help me with this issue.
