Description
I am getting a segmentation fault with:
print pbkdf2.pbkdf2_hex('asdfcasdfc','asdfasd',99999,20)
The commented out test from the RFC also seg faults:
print pbkdf2.pbkdf2_hex('password', 'salt', 16777216, 20)
If you are interested I put a gdb backtrace on:

Research direction
Start by reproducing the crash through pbkdf2.pbkdf2_hex with the high iteration counts shown in the issue, then inspect the linked gdb backtrace. The work is complete when both examples run without a segmentation fault and the relevant regression behavior is covered.
