Follow-up Comment #7, bug #51533 (project octave):

I'm using gcc 5.4 which explains why I'm not getting the
"stack-use-after-scope" warnings.

The first heap buffer overflow (from Sparse.cc-tst) is

READ of size 1 at 0x611000045eff thread T0
    #0 0x7f8f97a4cb7b in octave::lexer::fill_flex_buffer(char*, unsigned int)

Could you upload lex.ll so that I can match the exact source code against the
error report?
