NetBSD 9.2 Alpha: gdb failure
In attempting to debug the data conversion and floating-point issues
that I reported on this list yesterday, I found that gdb is unusable,
even for a trivial program that just prints a greeting:
% cat hello.c
#include <stdio.h>
int
main(void)
{
printf("hello, world\n");
return 0;
}
% cc -g -g3 hello.c
% gdb a.out
GNU gdb (GDB) 11.0.50.20200914-git
...
(gdb) b main
Breakpoint 1 at 0x1200008c8: file /u/sy/beebe/c/hello.c, line 6.
(gdb) run
Starting program: /local/build/cc/fx-0.0.40/a.out
limit: stacksize: Can't set limit (Operation not permitted)
terminate called without an active exception
[ 176884.2498815] sorry, pid 12842 was killed: orphaned traced process
Abort (core dumped)
My QEMU hardware configuration is:
% sysctl -a | grep ncpu
hw.ncpu = 2
hw.ncpuonline = 2
% sysctl -a | grep hw.phy
hw.physmem = -122880
hw.physmem64 = 4294844416
That is, 2 CPUs and 4GB DRAM.
% limit stacksize
stacksize 28672 kbytes
Even as root, I cannot increase the stacksize, and a hello-world
program needs only a few bytes on the stack.
On Debian 11 Linux with gdb 10.1.90, I can successfully single step
programs, set breakpoints, and examine variables.
Is gdb known to work on NetBSD 9.2 on a real physical Alpha system?
