Describe the bug The test case of tests/subsys/cpp/libcxx/ failed. (cpp.libcxx.cpp.libcxx.newlib.exception)

After bisect, the failure start from this commit : 615371900ed4165fefa5c03f7b6df34ac18bdefa, it previous commit 518dd32efee6ad999432327f316e3cf0feabe47b is good. "tests: cpp: libcxx: Use full version of newlib for testing"

Note: this issue only happened on acrn_ehl_crb board.

To Reproduce Steps to reproduce the behavior:

  1. Run this command from the zephyrproject: twister -p acrn_ehl_crb --device-testing --device-serial-pty="/opt/remotehw/acrn-test-pty.exp,ehlsku11" --west-flash="/opt/remotehw/remotehw-x86-acrn.sh,ehlsku11" -vv -T tests/subsys/cpp/libcxx/

2.Check handler.log in twister.out in directory to see the error log.

Expected behavior The test case is passed as expected.

Impact Not sure.

Note: this issue only happened on acrn_ehl_crb board.

@enjiamai Is the same failure also observed on acrn board?

stephanosio commented 3 years ago

@enjiamai Also you noted here that the failure starts from https://github.com/zephyrproject-rtos/zephyr/commit/518dd32efee6ad999432327f316e3cf0feabe47b.

Could you double check that it is actually from https://github.com/zephyrproject-rtos/zephyr/commit/518dd32efee6ad999432327f316e3cf0feabe47b and not https://github.com/zephyrproject-rtos/zephyr/commit/7e47ef281eccd7d1391bcdcf92affd7493c0dbd3?

Sorry, @stephanosio , after I double check it, the failed commit is start from 615371900ed4165fefa5c03f7b6df34ac18bdefa bad => 615371900ed4165fefa5c03f7b6df34ac18bdefa (tests: cpp: libcxx: Test with full and nano variants of newlib) good => 518dd32efee6ad999432327f316e3cf0feabe47b (tests: cpp: libcxx: Use full version of newlib for testing) good => f0e3280c61e6794038e01dcadc167943e8f1b990 (cpp: Fix C++ exception handling newlib dependency) good => 7e47ef281eccd7d1391bcdcf92affd7493c0dbd3 (linker: cpp: Fix C++ exception handling info section linking)

Hi @stephanosio , do you have any idea or suggestions about this issue? thanks!

I have not had much success trying to set up a test environment to reproduce this.

It is likely linker (script)-related issue (maybe the ACRN x86 build does some other magickery that is different from the conventional x86 build -- e.g. qemu_x86).

From https://github.com/zephyrproject-rtos/zephyr/commit/7e47ef281eccd7d1391bcdcf92affd7493c0dbd3:

The `.eh_frame_hdr` and `.eh_frame` ROM sections, which contain read-
only C++ exception handling information
enjiamai commented 2 years ago

Hi @stephanosio , thanks for your suggestion and comments, I found this testcase failed due to timeout.
