Issue #6592 has been updated by kosaki (Motohiro KOSAKI). Please confirm you are surely using fiddle (instead of plain DL). ext/dl is broken when the abi require proper function prototype for variadic arguments (e.g. x86_64). ---------------------------------------- Bug #6592: test_call_double(DL::TestDL) fails on ARM HardFP https://bugs.ruby-lang.org/issues/6592#change-27249 Author: vo.x (Vit Ondruch) Status: Open Priority: Normal Assignee: Category: Target version: ruby -v: ruby 2.0.0dev (2012-06-05 trunk 35922) [armv7hl-linux] Hi, I am observing following test suite error on armv7hl Fedora 17 [1] (but it seems that Debian suffers the same issues [3]): 2) Failure: test_call_double(DL::TestDL) [/builddir/build/BUILD/ruby-2.0.0-r35922/test/dl/test_dl2.rb:90]: Expected |0.1 - 2.1638932342073e-311| (0.1) to be < 0.001.

Issue #6592 has been updated by vo.x (Vit Ondruch). No I am not using Fiddle. Better to say, it is not up to me what I use. The test is written in such way that it is using DL no matter if libffi is present and if Fiddle might be used.

The test is written in such way that it is using DL no matter if libffi is present and if Fiddle might be used. I think we need to delete the CFunc code. The problem with that class is we cannot tell the return type, so it's impossible to set up a fiddle wrapper without using DL::CFunc in conjunction with DL::Function. I'll port these tests to Fiddle in preparation for rm'ing the dl implementation. > This is the callstack using GitHub ;) > > https://github.com/ruby/ruby/blob/trunk/ext/dl/cfunc.c#L340 > https://github.com/ruby/ruby/blob/trunk/ext/dl/lib... > https://github.com/ruby/ruby/blob/trunk/test/dl/te...

In other words, DL will be removed in 2.0, but this leaves 1.9.3 on ARM with broken functionality? It would be nice to document it somewhere at least, if this is the case.

It would be nice to document it somewhere at least, if this is the case. Thank you. Not so much broken, as replaced with Fiddle. I don't think the CFunc object is intended to be used directly (I couldn't find any usage in the wild). But yes, if you're using CFunc directly, it will break. :(
