[arm-gcc] internal compiler error

["Reddy, Suresh" <sureshr@xxxxxx>]

Hi paul,

We came across one more issue when we tried to compile 2.6.4 kernel with 3.4.0 tool chain. How ever we were able to compile 2.6.0 kernel without any issues. The error is as follows.

arm-linux-gcc -Wp,-MD,fs/.bio.o.d -nostdinc -iwithprefix include -D__KERNEL__ -Iinclude  -D__KERNEL__ -Iinclude  -Wall Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -fno-omit-frame-pointer -mapcs -mno-sched-prolog -mlittleendian -mapcs-32 -D__LINUX_ARM_ARCH__=6 -march=armv6 -mtune=arm9tdmi -mshort-load-bytes -msoft-float -Wa,-mno-fpu -Uarm -Os -Wdeclaration-after-statement    -DKBUILD_BASENAME=bio -DKBUILD_MODNAME=bio -c -o fs/bio.o fs/bio.c

make[1]: *** [fs/bio.o] Error 1

We are getting the same error for many files. 
Can you tell us how to fix this issue. 

Regards,
Suresh

Hi Paul,
	Can we have an early access via the cvs.  We are stuck due to this compiler issue.
warm regards

I believe we have already fixed this bug in CVS. We will be making a new 
release shortly which will include this fix.

For future reference a full bug report should contain the full commandline 
used to invoke gcc, and a preprocessed source file to allow us to reproduce 
the bug.

Use the -E option of gcc to create a preprocessed source file. The kernel 
build system prints commands as they are executed when invoked with
"make V=1".
