Visual Studio 2015 Update 3: Release 32bit: 54 tests failed

[anatoly-spb]

I have generated RxCpp Visual Studio 2015 solution with CMake 3.7.2 and built 32bit Release:

cd RxCpp
mkdir build
cd build
cmake -G "Visual Studio 14 2015" -T v140_xp ..
cmake --build . --target ALL_BUILD --config Release
cd build\test
ctest -C Release --no-compress-output -T Test

As the result the 54 tests failed with the same error (it does not matter with/without v140_xp):

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Any hints?

Thank in advance,

Hi @anatoly-spb,

Have you tried building the DEBUG version? Is the problem persists?

Thank you,
Grigoriy

[anatoly-spb]

@gchudnov, I have no problem with the debug build. There are all tests passed.

[gchudnov]

Investigating further, can you build a Release version for x64 without v140_xp toolset (like this)?
Does it fail on tests?

[anatoly-spb]

With the 64 bit release without v140_xp there is no problem, all tests passed.

[gchudnov]

hm.. so it looks v140_xp platform causes the problem. Is that right?

[anatoly-spb]

Let me check release 32 bit build without v140_xp.

[anatoly-spb]

I have checked. Actually we have problem with 32 bit release (it does not matter with/without v140_xp):

cmake -G "Visual Studio 14 2015"
cmake --build . --target ALL_BUILD --config Release

right, I was able to reproduce this issue {x86 and VS2017}.

Not sure I can make a quick fix. Need some time to look into the issue... :\

[anatoly-spb]

if it helps, I have catched segmentation violation in RelWithDebInfo:
