I get the following test failure since today. 95% tests passed, 1 tests failed out of 21 Total Test time (real) = 0.15 sec The following tests FAILED: 3 - assert-test (Failed) Errors while running CTest Output from these tests are in: /var/tmp/portage/dev-libs/libfmt-11.1.3/work/fmt-11.1.3_build-abi_x86_64.amd64/Testing/Temporary/LastTest.log Use "--rerun-failed --output-on-failure" to re-run the failed cases verbosely. * ERROR: dev-libs/libfmt-11.1.3::gentoo failed (test phase): * Tests failed.

One of the packages that was updated earlier is sys-apps/sandbox from version 2.43 to 2.44. And when I downgrade to sandbox-2.43, the libfmt tests pass again.

Looks like something is causing a segfault.

The issue is caused by the gtest ExecDeathTestSpawnChild function. This function allocates 2 pages of memory using mmap, and then passes this as the stack in a clone() call. The check_syscall function in libsandbox is currently using 4 pages of stack space to hold the absolute_path and resolved_path variables. I guess I'll have to revert back to using mmap for those variables instead.
