[ic] 4.9.4: [calc] and [currency] hosed - locale problem?

[interchange-users@icdevgroup.org (Toni Mueller)]

Hello,

we're running a 4.9.4 demo shop internally where we experiment.
This shop - foundation with red theme and soft goods - can be
used to illustrate a problem with [calc] and [currency] which
we also have with a different shop. To reproduce, select the
item 90773sh - Automotive Strategy Report - and view it in the
flypage. The item costs $89.99. Now change the flypage like this:


$ rcsdiff -u flypage.html

This renders on my computer like this:

Price: $89.99
error generating code:
15,84
14,3984
$14.00
$1.00
8,99
$8.00


Obviously, there's some gross miscalculation going on...
The language is set to LANG=de_DE@euro system wide, but
running Interchange like

$ env - LANG=C ~/interchange/bin/restart

still produces the same error. I'm running Perl 5.8 on Debian 'sid'.

What gives?


Best,
