I have the same problem with bwa-0.7.12 (I tried 0.7.4 and it works). Did you find a solution? my genome file does not contain spaces.

Based on previous encounters with such issues, please check if your genome file contains any spaces. Remove using sed or tr (if you find any).

See the answer from Vijay Lakhujani above. More specifically, remove whitespace from the fasta reference sequences (whitespace in fasta header is okay). See also: Burrows-Wheeler Aligner / Mailing Lists

If you have spaces in your header, use this instead:

sed -i 's/^[^>]\s*$//g' db/contaminants
