Created attachment 33103 [details]
single .ii file that triggers the ICE

Hi,

Trying out current Debian's gcc-snapshot (20140708) with a code that compiled fine with gcc-snapshot from a few weeks ago, I got:

internal compiler error: in lra_update_insn_recog_data, at lra.c:1219

Sorry, but I have no time now to narrow the cause :(
It can be reproduced with the attached .ii file and

/usr/lib/gcc-snapshot/bin/g++  -std=c++11 -fopenmp -pthread -Wfatal-errors -DNDEBUG -Ofast -march=native over_the_pole_2d.ii 

The native march seems to mean here (echo | /usr/lib/gcc-snapshot/bin/gcc -### -E - -march=native):

...
