Ldr: Actctx regression at Child process

Hi!
I'm tracking several bugs of apps which doesnt want to start and those apps leads to the LDR rewrite. Maybe the LDR rewrite didn't introduce the bug, but at least it has uncovered several others which are crashing a lots of apps (just try a query "ldr" or "actctx" in Jira, and you would be "surprised").

Tests shows this regression/uncovered bugs too, so it would be a nice opportunity to understand what's happening:

52445: Kernel32:actctx http://www.reactos.org/sites/all/modules/reactos/testman/detail.php?id=2272977&prev=2271225

52446(LDR rewrite): Kernel32:actctx http://www.reactos.org/sites/all/modules/reactos/testman/detail.php?id=2273853&prev=2272977

58492(Trunk): Kernel32:actctx http://www.reactos.org/sites/all/modules/reactos/testman/detail.php?id=6853168&prev=6817402

Go to the bottom of those tests.

In 52445 we can see that the test:
actctx.c:1126: child process manifest1
Has succeded.

In 52446(the rewrite) we can see that the test:
actctx.c:1126: child process manifest1
Has failed

In 58492(trunk) the situation is even worse:
We aren't even hitting
actctx.c:1126: child process manifest1

(the only reason to jump the test is because:
https://svn.reactos.org/svn/reactos/trunk/rostests/winetests/kernel32/actctx.c?revision=58492&view=markup#l1234 )

And also it shows:
actctx: 4 failures in child process

So at least there are 2 regressions.
I will try to find which revision introduced the second regression via Testman.
