Package: python3.13
Version: 3.13.14-1
Severity: important
X-Debbugs-Cc: [email protected]
Dear Maintainer,
I was trying to use GDB to debug a project I was working on but I quickly
discovered
that the debugger failed to start.
GDB and LLDB both don't start anymore, they throw the same error as below:
"gdb: symbol lookup error: /usr/lib/x86_64-linux-gnu/libpython3.13.so.1.0:
undefined symbol: XML_SetReparseDeferralEnabled"
I also found out other programs don't work, such as reportbug itself, they
throw this error:
"/usr/bin/python3: symbol lookup error: /usr/bin/python3: undefined symbol:
XML_SetHashSalt16Bytes"
I tried searching for a solution online and I was told to check if
libexpat.so.1 is properly linked,
I checked and it is.
It looks like the package python3.13 which is a dependency of the package
python3 in Unstable
has a bug which makes a program that relies on libexpat crash.
This bug happens on version 3.13.14, there is no issue on version 3.13.12,
which is running
on the laptop I'm writing this on.
Regards, Lorenzo.

Hi Lorenzo (2026.06.15_07:41:47_-0400)
"gdb: symbol lookup error: /usr/lib/x86_64-linux-gnu/libpython3.13.so.1.0:
undefined symbol: XML_SetReparseDeferralEnabled"
In private conversation, the culprit was found, a
/usr/local/lib/libexpat.so.1.
