[yocto] rpmdeps buffer overflow

[Marc Ferland]

Hi,

I'm creating a recipe for a precompiled SDK. This SDK contains various
precompiled libraries and executables. When I get to the packaging
step bitbake aborts with the following error:

ERROR: pylon-5.0.12-r0 do_package: Error executing a python function
in exec_python_func() autogenerated:

The stack trace of python calls that resulted in this exception/failure was:

Subprocess output:

Digging a little deeper, it looks like certain files cause rpmdeps to
blowup. For example, issuing:

rpmdeps --alldeps
/home/vagrant/build/tmp/work/aarch64-poky-linux/pylon/5.0.12-r0/packages-split/pylon/opt/pylon5/bin/libQt5Core.so.5.6.2

I get the expected:
  0 /home/vagrant/build/tmp/work/aarch64-poky-linux/pylon/5.0.12-r0/packages-split/pylon/opt/pylon5/bin/libQt5Core.so.5.6.2
    P libQt5Core.so.5(Qt_5_PRIVATE_API)(64bit)
    P libQt5Core.so.5(Qt_5)(64bit)
    P libQt5Core.so.5(Qt_5.0)(64bit)
    P libQt5Core.so.5(Qt_5.0)(64bit)
....

But running rpmdeps on one of their proprietary lib:
rpmdeps --alldeps
/home/vagrant/build/tmp/work/aarch64-poky-linux/pylon/5.0.12-r0/packages-split/pylon/opt/pylon5/bin/libPylonQtBase.so.1.0.0
*** buffer overflow detected ***:
/home/vagrant/build/tmp/work/aarch64-poky-linux/pylon/5.0.12-r0/recipe-sysroot-native/usr/lib/rpm/rpmdeps
terminated
Aborted (core dumped)

Any idea of what might be causing this?
