fn:matches (version 0.9.9 FPC3.2+) crashes on macOS

[Fravadona]

Given the followings XML:

<?xml version="1.0" encoding="utf-8" ?>
<a>X</a>

Here's what I get when I run xidel --xpath 'matches( /a/text(), "a|b" )' input.xml:

• nightly binary for macOS

I attached the build logs of Xidel using FPC 3.2.2 on Linux and macOS so that you can see the several new warnings that appear on macOS.

What does the debug version say? Or compiled with -g -gl? Or when it is run through gdb (after the error use commands disassemble and backtrace to get more information)?

I do not have a Mac to investigate this

I didn't find the debug version, compiling Xidel with -g -gl doesn't yield anything more than the previous crash message, and getting gdb to work on macOS is so convoluted... But here's the log:

gdb.log

Looks like that issue I encountered last month when updating fpc: https://github.com/BeRo1985/flre/issues/85

Try compiling it with the patched flre

Hi,

The patch fixes the macOS issue

Thank you
