It looks as though some files were compiled with GC 6.x and its
‘GC_REDIRECT_TO_LOCAL’ hack and eventually linked with GC 7.x.
Can you make sure this isn’t the case?

In particular, what does ‘pkg-config bdw-gc --cflags --libs
--modversion’ return?  Does it correspond to what’s actually used at
compile- and link-time?

As a last resort, I’d recommend installing libgc from source.

Thanks,
Ludo’.
