Resolution: fixed
Priority: normal
Severity: minor
Category: ~DO NOT USE (was: OCaml general)

Bug description

Full_Name: Mark Plesko
Version: 3.00
OS: Red Hat 7.0 and NT 4
Submission from: 207.86.147.86 (207.86.147.86)

The function

let f c = Int32.of_int (Int32.to_int c)

yields different (incorrect) results when using the native compiler (x86) rather
than the bytecode compiler. The conversions appear to be optimized away, thus
overflow never occurs.

Well spotted. This will be fixed in the next release (3.01).

Thanks for the bug report.
