Hi! Sorry commit 5494 not the problem in this situation. I have some research with next example code: echo "#include <cmath>" | g++ -x c++ -c - -m64 -mfpmath=both -std=gnu++11 -o /dev/null I try this code with different m32/m64 switches on different builds. First, I try Ruben's builds. He has only 32-bit builds and they are nomultilib. Code work fine on this builds. Next, I try all variants of gcc-4.7.2 builds from Mingw-builds project. Mingw-builds have multilib builds except dwarf. And have next picture: ------------------------------------------ | | -m32 | -m64 | ------------------------------------------ | dwarf2 | ok | --- | ------------------------------------------ | 32-sjlj | ok | fail | ------------------------------------------ | 64-sjlj | fail | fail | ------------------------------------------
This suggests that the error in 64-bit generated code. But where it can be? 2012/12/18 Алексей Павлов <alex...@gmail.com>: > I have two similar toolchains with next differences > - first toolchain builded with mingw-w64-trunk 5493 revision, second > - with 5496 revision. > - first toolchain builded without "-march -mtune", second - with > "-march=nocona -mtune=nocona" > First toolchain doesn't have issue, second toolchain have issue. > > I don't know where is mistake but I think it on this 3 revisions of > mingw-w64 trunk.
