Please submit a full bug report,

Please include the complete backtrace with any bug report.
See <http://gcc.gnu.org/bugs.html> for instructions.
Weirdly, when I execute the ICEing command on itself it ICEs, but when I add
-save-temps it doesn't and the resulting .i file compiles without error

--- Comment #1 from ktkachov at gcc dot gnu.org 2013-04-11 11:34:56 UTC ---
Created attachment 29856
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29856
Reduced testcase
ICEs with:
-std=gnu99 -Wall -Wstrict-prototypes -Wmissing-prototypes
-Wold-style-definition -Wextra -Wwrite-strings -fcx-fortran-rules
-ffunction-sections -fdata-sections -ftree-vectorize -funroll-loops -O2 -g
This is as much as I could reduce the testcase
