Hi Werner,

I've integrated successfully 1.6.0 release to debian sid and now it's waiting for sponsoring. Thanks for new upstream code.

It is not a bug to have variables with the same name in different source files. The bug was the missing keyword "static".

But there was a different bug that was not tolerated by GCC 10. It was same strange data type conversions in dav_coda.c. The resolution was to drop coda altogether because there is still fuse which is better suited anyway.

The new release 1.6.0 should fix all these problems. Please tell me if there are still problems with GCC 10.

Hi Werner,

I'd like to inform that this bug is still there since 1.5.6 after I check that dav_coda.c and dav_fuse.c also have a global debug variable. Please take a look and I'm responsible to update debian side as well.

Thanks for reporting.

The bug is fixed in the CVS-resources, branch rel-1-4-6.
It is just the declaration "static" in dav_coda.c, line 100, and dav_fuse.c, line 87.

Thank you very much for fixing this. We also found this problem in the Fedora mass rebuild today.

GCC 10 enables -fno-common bydefault, which breaks the build with:

/usr/lib/gcc/x86_64-pc-linux-gnu/9.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: dav_fuse.o:(.bss.debug+0x0): multiple definition of `debug'; dav_coda.o:(.bss.debug+0x0): first defined here
collect2: error: ld returned 1 exit status
