This seems to be a compiler bug as discussed here:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77629
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69481

Can you provide the info asked in the question template? Especially,

• Describe which system (OS, compiler) you are using.

• Describe which version of the library you are using (release version, develop branch).

It would be very helpful if you provide a minimal working example that triggers this crash so that others be able to reproduce it.
