Crash on module shutdown

[jocel1]

Hi,

I'm experiencing a crash in uopz with php 5.4.28 & uopz 2.0.4.
Basically I'm just adding uopz.so without calling any uopz function, and it crashes :

Program received signal EXC_BAD_ACCESS, Could not access memory.

I'll try to run it on a debug build to have more infos.

Thanks and regards,

I don't know if this could be related and if there is a known incompatibility, but I'm using ioncube loader (which is loaded before uopz).

Can you test without ioncube loaded please ?

It's impossible to do anything if ioncube is causing you a problem, it is closed source ... and a horrible horrible idea ...

[jocel1]

with a debug build (hence without ioncube), it seems there's no more crash during the shutdown...
Note that the tested project was not encoded, but the ioncube loader extension was loaded.

[krakjoe]

I can't do anything, sorry ...

Just so you know, if I could fix it, I would, ask anyone ...

But I want to say ... I really dislike ionCube, I dislike what it does and encourages, I think it's a dated, unnecessary, and damaging way to think ... code that you can rely on is code you can read, code you can change, code you can develop, code you can get help with.

ionCube stands in opposition to everything I hold up to be important.

TL;DR don't use ionCube
