Hi,

This bug still affects GCC 6. I haven't checked GCC 7.

It looks like the -gtoggle patch originates from Debian bug #634881. On that
basis it's likely this bug has affected every GCC version since at least 4.6.

The bug is that a-except.o has slightly different object code depending on
whether it is compiled with debug information enabled. The bug also seems to be
related to mips delay slots - if I compile a-except.o with -fno-delayed-branch,
there is no difference between stage2 and stage3.
