Odd error installing xdebug while building an 8.2 container in gitlab CI

Error description

When attempting to install xdebug in php:8.2 while building a container in gitlab CI I'm getting an odd error:

2: /tmp/pickle.tmp/xdebug/xdebug-3.2.0/src/lib/usefulstuff.c:1153: error: unterminated #else
2:  1153 | #ifdef ZEND_HASH_GET_APPLY_COUNT /* PHP 7.2 or earlier recursion protection */
2:       |
2: make: *** [Makefile:270: src/lib/usefulstuff.lo] Error 1The command '/bin/sh -c /usr/local/bin/install-php-extensions ${EXTENSIONS} @composer' returned a non-zero code: 1

The full output can be seen here: https://gitlab.com/portlandlabs/containers/-/jobs/3479191268

For some reason I'm able to build this container without issue locally, this issue only shows up in gitlab CI.

Docker image

php:8.2

Minimal Dockerfile

https://gitlab.com/portlandlabs/containers/-/blob/main/php/default/Dockerfile

where:
- `BASE_IMAGE` = `php:8.2`
- `EXTENSIONS` = `mbstring curl intl gd xml zip bz2 pdo_mysql xdebug redis amqp`

I've never seen such an error, and I can't reproduce it.

Maybe a temporary network occurred and the file downloaded from PECL are broken?
Have you tried to re-launch the job?

This error happened all day yesterday and this morning ~5 hours ago, I'm rerunning it now here: https://gitlab.com/portlandlabs/containers/-/jobs/3481480498

Could there be a cache on the server running the DIND container that needs to be cleared? This same server seems to do fine building 8.1+xdebug containers so I'm not sure what to poke at next.

I get the same error with a more minimal set up https://gitlab.com/portlandlabs/containers/-/jobs/3481570207:

One odd thing about this is the errors seem to point to lines of code that don't exist in certain files. One fatal error is directly related to this:

2: /tmp/pickle.tmp/xdebug/xdebug-3.2.0/src/base/filter.c:346:10: fatal error: mm.h: No such file or directory
2:   346 | #include "mm.h"
2:       |          ^~~~~~
2: compilation terminated.

Note that the line it's complaining about isn't actually in base/filter.c instead it's in lib/str.c so the relative include #include "mm.h" ends up fataling since it's relative to base rather than the intended lib directory.

• https://github.com/xdebug/xdebug/blob/3.2.0/src/lib/str.c
• https://github.com/xdebug/xdebug/blob/3.2.0/src/base/filter.c

Another interesting tidbit, installing xdebug directly using:

RUN pecl install xdebug
RUN echo "zend_extension=$(find /usr/local/lib/php/extensions/ -name xdebug.so)" > /usr/local/etc/php/conf.d/xdebug.ini

works fine, it's just installing xdebug with php-extension-installer having trouble

It looks like this issue exists when using pickle directly:

RUN /usr/local/bin/pickle.phar install xdebug --no-interaction

So the problem stems from there
