[BUG] ostest fails without returning the expected exit code

[tmedicci]

Description / Steps to reproduce the issue

In addition to the errors reported at #14722 (comment), there is an even critical issue regarding ostest for ESP32-S3 (and, eventually, for other archs): it fails without returning any error code after applying this PR.

How to Reproduce

Build/flash NuttX f2aeb5e56ff6ec7ba15958403289e462a8c84ab8 with Apps 0c467dc02d1f03f3f9f3defb16f36cb4f53b4c9d, with:

make -j distclean && ./tools/configure.sh esp32s3-devkit:smp && make flash EXTRAFLAGS="-Wno-cpp -Werror" ESPTOOL_BINDIR=./ ESPTOOL_PORT=/dev/ttyUSB0 -s -j$(nproc)

And run ostest :

signest_test: Simple case:
  Total signalled 1240  Odd=620 Even=620
  Total handled   1240  Odd=620 Even=620
  Total nested    3    Odd=3   Even=0

0

The firmware asserted, but the return code of ostest is still 0! This assertion occurs only with this firmware version. So, there are two open questions to be investigated: why is this test asserting after this PR and why ostest returns 0 even after assertion.

@tmedicci
i have a question.

ostest on esp32s3-devkit:smp doesn't work reliably for me, even with the change in question reverted.
it often hangs at seemingly random places. i have run it several times and it passed only once.

does it work better for you?

it seems it was because of an unrelated issue.

Hi @yamt , there were nested issues pending. I reported that ostest was failing because a recent change, but it seems to be fixed recently. Now (with #14751), the test runs successfully: apache/nuttx-apps#2737 (comment)

do you mean you have no idea how reliably it successes?

[yamt]

i've run the test several times, with and without an equivalent of #14722.
(i enabled assertions)
i couldn't reproduced the reported symptom.

Did you test with the exact references of nuttx and nuttx-apps repos I reported?

yes. at least a few times.

[yamt]

i suspect #14807 can explain the symptom. how do you think?
