Another SEGV signal problem found

[fCorleone]

When I run the program aubionotes. The address sanitizer showed this:

=================================================================
==7800==ERROR: AddressSanitizer: SEGV on unknown address 0x000000000004 (pc 0x7f0348775d3a bp 0x000000000007 sp 0x7fffc0b26750 T0)

Hi again,

Two problems here, when processing a corrupt file with negative samplerates:

• aubio_notes algorithm would keep trying even after pitch creation failed,
• aubio_source_wavread would not give up when samplerate < 0

These two should be fixed in the branch fix/negative_samplerate.

thanks for reporting, piem
