Bug #8358
Updated by nobu (Nobuyoshi Nakada) almost 10 years ago
I noticed TestSprintf#test_float http://ci.rubyinstaller.org/job/ruby-trunk-x86-test-all/1287/console ~~~ 1) Failure: TestSprintf#test_float [C:/Users/Worker/Jenkins/workspace/ruby-trunk-x86-build/test/ruby/test_sprintf.rb:193]: [ruby-dev:42551]. <"0x1p+2"> expected but was <"0x1p+1">. ~~~ This failure is due to r40404. And Actually, this issue is almost same to bug #8299. ruby_hdtoa function requires 53-bit precision but mingw32 compiler is 64-bit precision. There are 2 possible workarounds. 1. adding -msse2 -mfpmath=sse flag when compiling. 2. adding _control87(_PC_53, _MCW_PC) when running.
