It's a BSD extension not present everywhere.E.g. AIX doesn't have it, too.Fixed by wrapping the test in `#ifdef REG_STARTEND`.Tested on `amd64-pc-solaris2.11`, `sparcv9-sun-solaris2.11`, and`x86_64-pc-linux-gnu`.Differential Revision: https://reviews.llvm.org/D98425 List of files: /llvm-project-15.0.7/compiler-rt/test/sanitizer_common/TestCases/Posix/regex_startend.cpp Wed, 17 Mar 2021 08:56:19 +0000 Rainer Orth <ro@gcc.gnu.org> http://172.16.0.5:8080/history/llvm-project-15.0.7/compiler-rt/test/sanitizer_common/TestCases/Posix/regex_startend.cpp#ad294e57 [sanitizers] Fix interception of GLibc regexecPreviously, on GLibc systems, the interceptor was calling __compat_regexec(regexec@GLIBC_2.2.5) insead of the newer __regexec (regexec@GLIBC_2.3.4).The __compat_regexec strips the REG_STARTEND flag but does not report anerror if other flags are present. This can result in infinite loops forprograms that use REG_STARTEND to find all matches inside a buffer (sinceignoring REG_STARTEND means that the search always starts from the firstcharacter).The underlying issue is that GLibc's dlsym(RTLD_NEXT, ...) appears toalways return the oldest versioned symbol instead of the default. Thismeans it does not match the behaviour of dlsym(RTLD_DEFAULT, ...) or thebehaviour documented in the manpage.It appears a similar issue was encountered with realpath and worked aroundin 77ef78a0a5dbaa364529bd05ed7a7bd9a71dd8d4.See also https://sourceware.org/bugzilla/show_bug.cgi?id=14932 andhttps://sourceware.org/bugzilla/show_bug.cgi?id=1319.Fixes https://github.com/google/sanitizers/issues/1371Reviewed By: #sanitizers, vitalybuka, marxinDifferential Revision: https://reviews.llvm.org/D96348 List of files: /llvm-project-15.0.7/compiler-rt/test/sanitizer_common/TestCases/Posix/regex_startend.cpp Mon, 08 Mar 2021 10:09:42 +0000 Alex Richardson <Alexander.Richardson@cl.cam.ac.uk>
