[Sbcl-bugs] file-length 4 GB size problem

[Robert F. <rob...@me...>]

Hi,

When using

(file-length infile)

on a file bigger than 4 GB it returns the part above 4 GB, not the correct file size. I am using sbcl 1.2.12 on Arch Linux, the 64-bit build:

$ file /usr/bin/sbcl
/usr/bin/sbcl: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=35255041349f2eafd28d741b4a292a0fa972cdd1, stripped

To get around it I used

(filepos infile :end)
(filepos infile)

which gives me the correct file size.

Is there an optional way to use file-length, or is this a bug?

Thanks,
Robert Folland

SBCL 1.2.12 is not the current version of SBCL, 1.2.15 is.
