Fix it. Older versions of gas accepted bad .size directives and silently generated bad code. Thanks for your reply. I found the error, it was in my makefile: I removed CFLAGS += -fdata-sections http://gcc.gnu.org/onlinedocs/gcc-4.7.0/gcc/Optimize-Options.html#index-ffunction_002dsections-895 Now it compiles (I also removed -ffunction-sections) PFLAGS += --verbose CFLAGS += -mmcu=msp430f5437 #CFLAGS += -ffunction-sections #CFLAGS += -fdata-sections CFLAGS += -mmemory-model=medium OPTFLAGS += -Os Hmm, I may have jumped to the wrong conclusion. I was thinking that your problem was user asm, but this does look like a gcc or gas bug. If you put -ffunction-section and -fdata-sections back into CFLAGS, and also add -save-temps, then gcc should keep the source files passed to the assembler so you can have a look at them. What do the lines with errors look like? -- Alan Modra Australia Development Lab, IBM ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
[Bug ld/14528] Assertion failed while linking clang's object files under ARM

If so, then please can you put together a small test case (preferably consisting of just object files and a linker command line) so that I can try to reproduce the problem.

Could this be what is happening here. Ie, are you linking against a thumb encoded version of _start ? If you disassemble the code at _start, what does it look like ?

Which explains why the bottom bit is set. I am not familiar with the ARM processor on the PI. Maybe it is incapable of executing these instructions ? Perhaps you should specify the ARM processor type when you compile your program ?
