This code hangs up on amdMmx if it is compiled by dmd 2.069.2, but works well if compiled by dmd 2.068.2. void main() { import core.cpuid; import std.stdio; if (amdMmx) writeln("amdMmx"); } Configuration: Microsoft Windows 7 Professional 6.1.7601 Service Pack 1 64-bit CPU Intel(R) Core(TM) i7-2640M CPU @ 2.80GHz, 2801 МГц NVIDIA NVS 4200M
