Jan, I removed the CFLAGS and LDFLAGS, with configure command: ./configure --build=i686-pc-linux-gnu --host=arm-linux-gnueabihf --with-core=cobalt --enable-smp --enable-lazy-setsched --enable-debug=symbols
But the issue still remains. I changed the failed test case as below, the issue still exists. 226 static void autoinit_simple_conddestroy(void) 227 { 228 >-------pthread_cond_t cond = PTHREAD_COND_INITIALIZER; 229 #if 0 230 >-------pthread_cond_t cond2 = PTHREAD_COND_INITIALIZER; 231 >-------unsigned int invalmagic = ~0x86860505; // ~COBALT_COND_MAGIC 232 233 >-------memcpy((char *)&cond2 + sizeof(cond2) - sizeof(invalmagic), 234 >------->-------&invalmagic, sizeof(invalmagic)); 235 236 >-------smokey_trace("%s", __func__); 237 #endif 238 >-------check("cond_destroy", cond_destroy(&cond), 0); 239 //>-----check("cond_destroy invalid", cond_destroy(&cond2), -EINVAL); 240 } I'll try QEMU later to see if the issue also exits in QEMU. BTW, I saw some below warnings in compiling, do they have any relationship with the issue? /bin/bash ../../../libtool --mode=install /usr/bin/install -c smokey_net_server '/home/data/nfs_test//usr/xenomai/bin' libtool: warning: '../../../lib/cobalt/libcobalt.la' has not been installed in '/usr/xenomai/lib' libtool: warning: '../../../lib/cobalt/libmodechk.la' has not been installed in '/usr/xenomai/lib' 2021-05-10 15:35 GMT+08:00, Jan Kiszka <jan.kis...@siemens.com>: > On 10.05.21 09:20, Fangsuo Wu wrote: >> Jan, >> Thanks for your reply.
