The plan would be to: - Check whether <execinfo.h> is present. - Check whether the backtrace() function can be linked, either from libc, or from libexecinfo (some systems provide it there) - Define PAS_HAVE_BACKTRACE and HAVE_BACKTRACE accordingly. - Change the guards in libpas and WTF to PAS_HAVE(BACKTRACE) and HAVE(BACKTRACE) accordingly. 2156459 1 alexbdamac 2025-11-04 17:42:50 -0800 Pull request: https://github.com/WebKit/WebKit/pull/53431
