Package: gdc-4.3
Version: 1:1.046-4.3.4-5
Severity: serious
The MD5-sums calculated by std.md5 are seriously broken - they're not
only wrong, they're different on each run..
gdc-4.1 and the closed-source dmd do *not* have this bug. Because
md5.d in the gdc-4.1 and gdc-4.3 package sources are identical I file
this as a bug in the compiler, not libphobos.
I consider this a serious bug because it makes std.md5 unusable and
probably affects other code as well (why should it only break the MD5
code).
I attached a simple testcase to demonstrate this bug. When it's build
with gdc-4.1 I get the following output:
"900150983CD24FB0D6963F7D28E17F72", when it's built with gdc-4.3 I
get:
"9BB8D85B9EC69BAAE48AFD6DC642C4B7
Error: AssertError Failure md5test.d(8)"
or "73295B9A9D13003D9E6065260759FBD4
Error: AssertError Failure md5test.d(8)"
... (a different sum on each run).
Cheers,
- Daniel
