hledger 1.25 inferred the market price correctly but produced an incorrect valuation (note both amounts are negative):

hledger 1.26 fixed the valuation, but now incorrectly infers a negative market price:

I had several of those odd double negative entries (generated by csv rules, unknowingly), and this caused hledger 1.26 to report an incorrect balance in one of my reports. A minimal example:
$ hledger-1.25 bal b -N -X A --infer-market-prices
A -1 b
$ hledger-1.26 bal b -N -X A --infer-market-prices
A 1 b
