#157 Floating point exception when running te

[Anonymous]

Hi,

I encountered some Floating point exceptions while
running the tests.

The problem was division by zero in lib/progress.c.
A quick fix (likely not logically correct) is

Cmd : diff -C 3 lib/progress.c.orig lib/progress.c
*** lib/progress.c.orig Wed Oct 31 09:45:47 2001
--- lib/progress.c Wed Feb 6 14:35:57 2002
***************
*** 279,285 ****
--- 279,289 ----
/* Calculate the average speed the last
'countindex' seconds */
data->progress.current_speed =
(data->progress.speeder[nowindex]-
+ #if 0 /* divide by zero errors */

data->progress.speeder[checkindex])/((double)span_ms/1000);
+ #else
+
data->progress.speeder[checkindex])/(span_ms?((double)span_ms/1000):1.0);
+ #endif
}
else
/* the first second we use the main average */

Cmd : make test
[ -f test1 ] || ln -s ./test* .
srcdir=. /usr/bin/perl -I. ./runtests.pl -s -a

Thanks for reporting!

This problem was fixed over two months ago:
