Zigackly! This is how backtrace( ) is implemented
on Win32 for GCJ right now and that's why it's
asking for trouble if you try to compile Java programs
with -fomit-framepointer.
In fact, isn't this how glibc's backtrace( ) is
also implemented on x86-Linux?
But Bryce wants to avoid having to call backtrace( )
and use libgcc's unwinder interface instead and hence
my query.
