Segmentation Fault using File::sysseek

[foranje@…]

Using the sysseek method of a file always seems to result into a Segmentation fault using MacRuby. Using the same code with regular Ruby works fine.

test.rb

file = File.new("test.txt")
file.sysseek(2, IO::SEEK_SET)
print file.sysread(5)
file.close

test.txt

blaatblaatblaatblaatblaat

Result when executing the file using MacRuby:

Segmentation fault

If I comment out the sysseek line, it gives no error. So the sysseek seems to be the issue.

Laurent, the stack trace is the following:

Is that the problem with the NSNumber bridge?

Should be fixed in r3903.
