Topic: arm toolchain
Are there any known problems with the arm toolchain including using optimization? I've only compiled one thing for my chumby (rsync) and saw lots of strange behavior. Using gdb I was able to see that in fmtfp (a floating point emulation portion of lib/snprintf.c in rsync) had a value change between two lines of code when it's not touched. This was causing major problems including some random segfaults.
I could not reproduce it with exporting CFLAGS to exclude -O2 which was on by default for the rsync build.
