--- Comment #2 from Svante Signell <svante.signell at gmail dot com> --- Hi, when compiling ./build/atlas-base/src/blas/gemm/KERNEL/ATL_cNCCUmmNN.c from Debian atlas 3.10.2-3 on GNU/Hurd the ICE happens (twice): ATL_cNCCUmmNN.c:3856:1: internal compiler error: Maximum number of LRA constraint passes is achieved (30) } ^ libbacktrace could not find executable to open Please submit a full bug report, with preprocessed source if appropriate. gcc version is Debian 4.9.1-15. It might be so that the input data for this generated file is non-sensical, the CPU speed detection does not work on Hurd. Nevertheless, the compiler should not error out with an ICE? Thanks!
