Description

In the file /php-src/Zend/Optimizer/escape_analysis.c, at line 387, a pointer variable named ees is defined. At line 411, this variable allocates a dynamic memory area using the do_alloca function. If the conditional statement at line 412 evaluates to false, it indicates that the dynamic memory allocation pointed to by ees was successful. However, if the conditional statement at line 416 evaluates to true, the function will return at line 417, bypassing the deallocation of the dynamic memory area pointed to by ees at line 532. This situation constitutes a memory leak, as illustrated in the diagram below:

Is this some kind of bot?

While there are certainly bots like these, I think this is a real person using static analysis, given the varying wording between the issues.

Why don't we have his static analysis tools? 😆

[nielsdos]

Actually, I sometimes run static analysis tools on PHP. That's how I started in my early contribution days actually.
I even experiment with my own tools on PHP.
