------- Comment #4 from ramana at gcc dot gnu dot org 2009-12-09 16:04 -------
Do you still see this problem ? Can you provide a backtrace or some more
information about this one ?
I don't see this as of 4.4 from yesterday.
mkdir test.gch
gcc -x c-header -marm -fmem-report -ftime-report -c -march=armv5te test.h -o
