pocketsphinx iOS App crash due to memory allocation error in ps_search_step()

[nayan kalita]

Hi ,

I am developing an iPhone app using pocketsphinx. The app crash due to memory allocation error for the function call ps_search_step after processing some files.

while ((nfr = acmod_process_raw(acmod1, &bptr, &nread, TRUE)) > 0) {
while (acmod1->n_feat_frame > 0) {
ps_search_step(ngs1, acmod1->output_frame);
acmod_advance(acmod1);
}
fprintf(stderr, "\nprocessed %d frames\n", nfr);
}

Following is the crash log.
