Hi Mathieu, I'm getting rseq selftest build failure with glibc 2.30, which added gettid():
param_test.c:18:21: error: static declaration of 'gettid' follows non- static declaration 18 | static inline pid_t gettid(void) | ^~~~~~ In file included from /usr/include/unistd.h:1170, from param_test.c:11: /usr/include/bits/unistd_ext.h:34:16: note: previous declaration of 'gettid' was here 34 | extern __pid_t gettid (void) __THROW; | ^~~~~~ BR, Tommi
