The following two stacks come from the crashreporter (the internal bug ID's are
130934 and 130690). The stacks look like this:

===============================================
The first has a report count of 37 and the second of 6.
The respective code part is
int MyThes::binsearch(char * sw, char* list[], int nlst)
{
int lp, up, mp, j, indx;
lp = 0;
up = nlst-1;
indx = -1;
if (strcmp(sw,list[lp]) < 0) return -1;
if (strcmp(sw,list[up]) > 0) return -1;
The first crash takes place in the line with the first 'strcmp' and the second
crash in the following line.
Looking in the source code of m172 the line
int idx = nw > 0 ? binsearch(wrd,list,nw) : -1;
seems to already take care of the second crash.
But it seems to me 'list' should be checked against NULL as well to guard
against the first crash.
