10.4.2 IDE Compilation Memory leak

[Lars Fosdal 1792]

I have a Programs Group containing the projects that I work with on a daily basis.

In versions  prior to 10.x - sometimes before committing a possibly breaking code change, I would do a build all on that group.

There was an older version that also would run out of memory, but eventually that got fixed, but now it seems that error is back.

I hadn't really used this for some time, since the build server does it faster than I can, but I was going to benchmark 10.4.2 vs 10.4.1.
(Note that the time axis on the charts below are not comparable).

 

10.4.1 churns through the first 8 projects before it stops on an out of memory error, consuming 3.25Gb.

 

 

10.4.2 crashes out hard (IDE goes *poof*) at peak 3.42Gb

 

I wonder what logic it is that governs when the IDE should release generated code or not?

 

Each arrow represents when it starts compiling a project in the project group.
Large VCL app,
Moderate VCL app,
Small VCL app,
Small VCL app,
Moderate VCL app, 

Small VCL wrapper around service code,
Service without GUI,
Small VCL wrapper around service code (OOM).

If it had released every time, we would not have this problem.
 

On the bright side, 10.4.2 is a slightly faster compiler.

Complaint 1: The IDE should not run out of memory when compiling a project group.

Complaint 2: The IDE should - if it runs out - handle it gracefully and not crash out.

Maybe same problem: https://quality.embarcadero.com/browse/RSP-32793

The IDE is a 32-bit app using the large memory "hack" that allows it to use 3Gb instead of two. 
See https://cc.embarcadero.com/Item/24309 for an example.
@emailx45 The ISLC application you suggest is irrelevant. My laptop has 32 Gb.

I commented on this one. https://quality.embarcadero.com/browse/RSP-32768

https://quality.embarcadero.com/browse/RSP-32792 and 93 are duplicates of that one, it seems.
