 I am working on a bounds checking patch for gcc, and while testing it
on bison-1.875 testsuite, it flagged 8 array access bugs.
I inspected the source to confirm, and it turns out they were all similar
in nature. In each case for a given array e.g buffer of size N, accessing
elements at index >= N wasn't guarded against. The
bounds checker halts the program when access to index N is attempted.
The error message produced by the checker is in the attached testsuite.log
Please could you check this and confirm.
