Package: ledger Version: 3.3.2-1+b4 Severity: normal Dear Maintainer,
please find a script below to reproduce a segmentation fault when
calling ledger convert:
```
#!/bin/sh
set -e
ledger --version
cd /tmp
rm -rf ledger-segfault && mkdir ledger-segfault
cd ledger-segfault
# create three example files (1 ledger, 2 csvs to be imported):
cat << EOF > test.dat
tag CSV
tag Imported
tag reference_id
assert value =~ /^[*]{8}[0-9]{19}/

# call ledger convert for the final1.csv (SUCCESS):
ledger convert final1.csv --input-date-format "%Y-%m-%d" --invert --account
"Assets:Bank One" --rich-data --file test.dat --now 2026-03-09
# append ledger convert output of final1.csv to ledger (SUCCESS):
ledger convert final1.csv --input-date-format "%Y-%m-%d" --invert --account
"Assets:Bank One" --rich-data --file test.dat --now 2026-03-09 >> test.dat
# call ledger convert for the final2.csv (SEGFAULT):
ledger convert final2.csv --input-date-format "%Y-%m-%d" --invert --account

```
Running the script through strace gives me this:

```
which doesn't tell me much.
Commenting out the regex tag assertion for reference_id in test.dat
solves the problem, so I _assume_ it has something to do with it.
Might need forwarding upstream, if the issue persists on newer versions
of upstream. I haven't tested newer upstream versions.
Thank you for looking into this and your work on the package!
