Description Martin Liska 2021-01-04 06:57:13 UTC

As reported here:
https://bugzilla.suse.com/show_bug.cgi?id=1180306

```
It introduces the file "/etc/profile.d/debuginfod.csh" which produces an error during shell initialization, so that startup scripts are not properly run.

Workaround: chmod +t /etc/profile.d/debuginfod.csh

This makes sure that the file is not used in csh startup.

Current content of file:
 ----

setenv DEBUGINFOD_URLS "$DEBUGINFOD_URLS "
 ----

Suggested alternative content for file:
 ----

if ( $?DEBUGINFOD_URLS ) then
    setenv DEBUGINFOD_URLS "$DEBUGINFOD_URLS "
endif
 ----

This change avoids evaluating an undefined variable.
```

Has this been resolved by:

commit 911ac29b9eed3c66bba60eda6af8e5de62607e5c
Author: Dmitry V. Levin <ldv@altlinux.org>

    config: do not define DEBUGINFOD_URLS environment variable unnecessarily
    
    Before this change, when elfutils was configured without
    --enable-debuginfod-urls, the installed profile.d/debuginfod.sh and
    profile.d/debuginfod.csh scripts used to define the DEBUGINFOD_URLS
    environment variable as an non-empty string containing spaces, making
    all libdebuginfod users do extra work.
    
    Change these scripts to avoid defining the DEBUGINFOD_URLS environment
    variable unless configured using --enable-debuginfod-urls.

All right, thank you for the pointer.
