Bug #8358

Updated by Nobuyoshi Nakada 10 months ago

I noticed TestSprintf#test_float


1) Failure:
TestSprintf#test_float [C:/Users/Worker/Jenkins/workspace/ruby-trunk-x86-build/test/ruby/test_sprintf.rb:193]:
<"0x1p+2"> expected but was

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.
