Package: wcc
Version: 0.0.2+dfsg-3
Severity: serious
Dear wcc maintainers,
The wcc autopkgtests try to dlopen some PIE executables (namely
/usr/bin/ssh). This has never been really supported, and this fails with
an error message in recent glibc versions. This cause the autopkgtest to
fail:
| autopkgtest [11:11:14]: test command1: ./debian/tests/wsh-ssl.wsh /usr/bin/ssh
| autopkgtest [11:11:14]: test command1: [-----------------------
| ERROR: dlopen() /usr/bin/ssh: cannot dynamically load position-independent
executable
| ERROR: dlopen() of patched file! //tmp/.wsh-1902/ssh: cannot dynamically load
position-independent executable
| WARNING: No binary loaded in memory. Try loadbin(). For help type
help("loadbin").

(see https://ci.debian.net/data/autopkgtest/testing/amd64/w/wcc/3942223/log.gz)
You can see reason for disabling dlopening PIE binaries in this upstream
bug report:
https://sourceware.org/bugzilla/show_bug.cgi?id=24323
It is unclear to me what this change means for the wcc testsuite and for
the usability of the wcc package. Could you please explain me how is it
used?
Thanks,
Aurelien
