I'm encountering an internal compiler error with the gcc 4.3.0 release. I don't think this is a duplicate of any other bugs.
Here is the command and subsequent output: powerpc-eabispe-gcc -I../ -I/home/patrick/src/e7/prex -I/home/patrick/src/e7/prex/usr/include -I/home/patrick/src/e7/prex/include -nostdinc -fsingle-precision-constant -mabi=no-spe -gdwarf-2 -Os -ansi -fno-strict-aliasing -Wall -Wundef -Wstrict-prototypes -Wpointer-arith -std=gnu99 -fno-stack-protector -Wno-variadic-macros -D__ppc__ -D__e7__ -D__ARCH__=ppc -D__PLATFORM__=e7 -Uppc -Ue7 -fno-omit-frame-pointer -DDEBUG -g -Wsign-compare -Werror-implicit-function-declaration -I../comms/lwip/include -I../comms/lwip/prex/include -I../comms/lwip/include/ipv4 -v -save-temps -I../include -c -o ../test/test_xcp_eth.o test_xcp_eth.c Using built-in specs.
