Bug ID: 486486
Summary: Build fails with LTO
Classification: Applications
Product: kmymoney
Version: 5.1.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: buildsystem
Assignee: kmymoney-devel at kde.org
Reporter: eschwartz93 at gmail.com

build.log
I tried to build with the following *FLAGS to optimize the build: `-flto=4
-Werror=odr -Werror=lto-type-mismatch -Werror=strict-aliasing`
Note the -Werror=* flags are used to help detect cases where the compiler tries
to optimize by assuming UB cannot exist in the source code -- if it does exist,
ordinarily the code would be miscompiled, and this says to make the
miscompilation a fatal error.
I got this error:
```
