Hello list,

running some scripts caluclating via bc() the expression shown below:

bc -e '6582031 - 1048576 - 0 - 409600 - 1024 - 40 - 4096' -e quit

results on recent CURRENT ( FreeBSD 13.0-CURRENT #80 r362884: Thu Jul  2 10:08:23 CEST 2020
amd64) with an empty result, while it is calculated correctly on 12-STABLE (FreeBSD
12.1-STABLE #67 r362719: Sun Jun 28 09:59:20 CEST 2020 amd64) and a CURRENT dated from  Sun
Jun 28th (have no revision number anymore, the expression above was calculated correctly on
the same box which now has r362884 and is failing).

Whats wrong?

Kind regards,

oliver
