The line numbers in the backtrace don't seem to correspond to current sources.
for instance line 866 is the definition of find_source, not the location of one
of the two bsearch calls.
which of the two bsearch calls is blowing up?
this one:
name_map = (name_map_t *)bsearch
(file_name, names, n_names, sizeof (*names), name_search);
or this one:
name_map = (name_map_t *)bsearch
(canon, names, n_names, sizeof (*names), name_search);
What are the values being passed to the bsearch call?
Oh, I see that it appears the string being passed to 'find_source' is
unreadable:
#2 0x08056d88 in find_source (file_name=0x80a2f70 <error reading variable>)
at /vol/gcc/src/hg/trunk/local/gcc/gcov.c:866
What does gcov-dump -lo tell you about the gcno file?
