There are two possible reasons for this. ==29681== 1. Your program has a bug and erroneously jumped to a non-code ==29681== location. If you are running Memcheck and you just saw a ==29681== warning about a bad jump, it's probably your program's fault. ==29681== 2. The instruction is legitimate but Valgrind doesn't handle it, ==29681== i.e. it's Valgrind's fault. If you think this is the case or ==29681== you are not sure, please let us know and we'll try to fix it. ==29681== Either way, Valgrind will now raise a SIGILL signal which will ==29681== probably kill your program. ==29681== Thread 7 Threadpool work: ==29681== Invalid write of size 4 ==29681== at 0x100E6658: handle_signal_exception (exceptions-ppc.c:717) ==29681== by 0xFEAD31F: __slow_ieee754_sqrt (in /lib/powerpc-linux-gnu/libm-2.22.so) ==29681== Address 0x813e6b4 is on thread 7's stack ==29681== Reproducible: Always -- You are receiving this mail because: You are watching all bug changes.
