About 12 are expected. The error will be in the last command line, so
only the last few lines of the file are relevant: to wit

Error: pweibull(seq(1, 50, len = 1001), 2, 3, log = TRUE) < 0 is not TRUE
for which you would need to investigate the output of
pweibull(seq(1, 50, len = 1001), 2, 3, log = TRUE)
and I guess that this is an accuracy problem in the runtime (libc).
