[Bioc-devel] Spurious "dims [product 864] do not match the length of object [432]" on macOS

[Neumann, Steffen]

Hi,

for several years xcms is suffering from absolutely spurious 
issues on macOS.

There is no pattern regarding release/devel, R versions, different
macOS machines like merida1 in 2019, to machv2 today and a few
occurances inbetween. The tssue usually resolves itself after a few
days without any code change. 

Interestingly, 864=432*2, so something is duplicated somewhere. Also,
today was the first time I saw BiocParallel mentioned near the error,
see below. 

=> Has anyone observed such a domension mismatch, maybe in other
packages, and has any idea what could be the (spurious) cause ?

Yours,
Steffen
