Description of problem:

I am working on developing Ceph. I have a topic branch and GCC crashes out when compiling it. When I try to use CLang it works fine.

Version-Release number of selected component (if applicable):

% gcc --version
gcc (GCC) 6.3.1 20161221 (Red Hat 6.3.1-1)
Copyright (C) 2016 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

How reproducible:

It is consistent, at least on this machine.

Steps to Reproduce:
1. git clone git://github.com/adamemerson/ceph
2. cd ceph
3. git checkout wip-FINISH-HIM
4. ./do_cmake.sh
5. cd build
6. make VERBOSE=1

Expected results:

The program compiles. Or at least gives an error other than reporting a crash and sending me to this bugzilla.

Additional info:

I have had similar problems before, often changes in master will make them go away again, but I suspect there's some failure in GCC that is being tickled under some obscure circumstance.

Comment 1 Jakub Jelinek 2017-06-07 16:39:24 UTC

Can't reproduce with the preprocessed source you've provided, either with gcc-6.3.1-1.fc25 or current trunk.

Comment 3 Jakub Jelinek 2017-06-30 12:58:25 UTC

Haven't managed to reproduce it even with additional --param ggc-min-heapsize=0 --param ggc-min-expand=0 (which triggers the GC at all ggc_collect spots).
So it is hard to debug.
Solely from the above backtrace, it seems 0x725f73693a3a6474 which is being dereferenced as a pointer is actually a portion of a string:
"td::is_r"
The above suggests that this is because some cp_token has tree_check_value pointing to a vector where one of the elements has checks a vector where one of the elements has binfo field which is the above invalid pointer or one of its TREE_CHAIN is.  But it is impossible to find out why that happened without reproduction.
So, if you can reproduce somewhere and can give me access to that box, I can debug further, otherwise there is nothing that can be done here.
