Hi everybody, I'm debugging a library that implement some nasty protocol. This library is used by some JNI library which exports the native library to Java world. By the way I'm running on ARMv7. Well, some times, at random times, that library crashes. The problem is that I can't get stacktrace. Not from JVM's fatal errors logs, not from core dumps, not from libSegFault... I'm using "-g -rdynamic -funwind-tables -mapcs-frame" compiler options but still I can't get a stacktrace. I've tried using glibc backtrace too. What I don't tried yet: libunwind, valgrid and making kernel do the stacktrace. The cool part is that when I ran my library outside from the JVM (with native application) I do get backtraces! [Damn Java] I'm here to ask: Is it possible to make kernel print the stacktrace for some userspace application when it crashes? I saw USER_STACKTRACE_SUPPORT but can't find any help from it's Kconfig. I saw this https://kernelnewbies.org/FAQ/StackTrace and this http://processors.wiki.ti.com/index.php/Enabling_Stack_Dumping_in_Linux_Kern... but can't find "Kernel hacking -> Verbose kernel error messages" even with "Kernel hacking -> Kernel Debuggin" enabled. Any help is appreciated! Thanks !!! -- "Do or do not. There is no try" Yoda Master
