--- Comment #4 from Stephen Casner <casner at acm dot org> ---
I verified that the compilation of chrono:544 is the first time in the build
that the failing assert is executed, so that likely implies that the proble=
m is
general and not specific to the particular source code.

The only mentions of COMDAT in the pdp11 backend are the macros

#define TARGET_CXX_CLASS_DATA_ALWAYS_COMDAT hook_bool_void_false
#define TARGET_CXX_LIBRARY_RTTI_COMDAT hook_bool_void_false

These are in the direction that make the assert true rather than false, so
changing those to the default hook_bool_void_true wouldn't help (and would
presumably cause something else to fail).

I'm way out of my league here, so any suggestions would be appreciated.=
