Error: Tried to insert kmer 9318400 starting at position 143779831, number of slots 65. Position: 65

[fgp]

When trying to map against mm10, while building the "ref table", NGM version 0.5.5 (installed via BioConda) aborts with the error:

Tried to insert kmer 9318400 starting at position 143779831, number of slots 65. Position: 65

Weirdly enough, retrying multiple times always produced similar errors, but for a different position and number of slots. The error does not occur with NGM 0.5.3 (also installed with BioConda). 0.5.4 was not tested, since it's not available through BioConda.

The only commit between 0.5.3 and 0.5.5 that touches code in src/PrefixTable.cpp seems to be 54ee69fd5051, but I can't seen an obvious problem in that commit...
