User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36 Edg/83.0.478.56

Steps to reproduce:

I'm a beginner so I thought I might be doing something wrong here. When I posted this in riot, they suggest that I submit a bug report.

Windows 10 64 bit
16.0GB Memory

Open MozillaBuild, clone the mozilla-central repo and run gtest without touching any code.
hg clone https://hg.mozilla.org/mozilla-central/
cd mozilla-central
./mach gtest

Actual results:

[----------] Global test environment tear-down
[==========] 5494 tests from 389 test cases ran. (696132 ms total)
[ PASSED ] 5493 tests.
[ FAILED ] 1 test, listed below:
[ FAILED ] TestUCRTDepends.AppDir

If I do
./mach gtest TestUCRTDepends.AppDir

I get:
[==========] Running 1 test from 1 test case.
[----------] Global test environment set-up.
[----------] 1 test from TestUCRTDepends
[ RUN ] TestUCRTDepends.AppDir
d:/dev/mozilla-source/mozilla-central/toolkit/library/gtest/TestUCRTDepends.cpp(56): error: Expected: (hFind) != (((HANDLE)(LONG_PTR)-1)), actual: FFFFFFFFFFFFFFFF vs FFFFFFFFFFFFFFFF
[ FAILED ] TestUCRTDepends.AppDir (1 ms)
[----------] 1 test from TestUCRTDepends (2 ms total)

[----------] Global test environment tear-down
[==========] 1 test from 1 test case ran. (8 ms total)
[ PASSED ] 0 tests.
[ FAILED ] 1 test, listed below:
[ FAILED ] TestUCRTDepends.AppDir

Expected results:

I thought everything should pass the tests.
