Hi, I've upgraded to 5.1.1 due to bugs in 4.x, but debugging almost any program is unbearably slow. I've attached some detailed debug output; here is a summary: In the file gdb_commands I put: break main r k q Compare running the command "time strace -c gdb -x gdb_commands src/.libs/gideon" under 4.18 and 5.1.1: 4.18: % time seconds usecs/call calls errors syscall ------ ----------- ----------- --------- --------- ---------------- 44.44 0.153028 23 6763 ptrace real 0m4.299s user 0m2.550s sys 0m0.810s 5.1.1: % time seconds usecs/call calls errors syscall ------ ----------- ----------- --------- --------- ---------------- 98.07 26.668416 27 986910 ptrace real 1m9.949s user 0m20.750s sys 0m40.540s Note the nearly 1 million calls to ptrace with 5.1: more than a hundred-fold increase compared to 4.18. If you need more detailed strace output or any other info, let me know. Thanks, John
