Bug 1651 - EIGEN_GEBGP_ONESTEP: inconsistent operand constraints in an ‘asm’
Summary: EIGEN_GEBGP_ONESTEP: inconsistent operand constraints in an ‘asm’
Status: RESOLVED DUPLICATE of bug 1643

Description Matthew Woehlke 2018-12-25 19:31:11 UTC
While trying to compile some code¹ that uses Eigen, I am receiving the following build error(s):

   error: inconsistent operand constraints in an ‘asm’
   (...several more of the same macro with different argument on subsequent lines...)

It seems I am not the only one: — in arrows/core/triangulate.cxx)

This appears to have started happening "recently", though it's been a while since I did a clean build of my code, so it's hard to say exactly when it started. Given the CentOS report, it seems plausible this is a compiler problem rather than an issue in Eigen itself?
Comment 1 Matthew Woehlke 2018-12-25 19:34:25 UTC
Note: downgrading from eigen3-devel-3.3.6-1.fc29.noarch to eigen3-devel-3.3.5-2.fc29.noarch seems to have "fixed" the problem.
Comment 2 Christoph Hertzberg 2018-12-25 19:54:25 UTC
Should be fixed in 3.3.7 as well
