I working on a small test program using Jay McCarthy's zmq FFI bindings.
I'm getting a segfault with this message:
SIGSEGV MAPERR si_code 1 fault on addr 0x285
Is there any guidance on how to spot the cause? Here's what I have done so far
run racket with gdb - as gdb racket
In the gdb console...
handle SIGSEGV nostop
handle SIGSEGV noprint
(those last two seem to be necessary for my script to run at all)
And finally I run my racket file in gdb as follows
run -tm example.rkt
I then get this message, after my code actually starts:
SIGSEGV MAPERR si_code 1 fault on addr 0x285
Program received signal SIGABRT, Aborted.
[Switching to Thread 0x7fffe77fe700 (LWP 20186)]
0x00007ffff713e1e5 in __GI_raise (sig=sig@entry=6)
at ../nptl/sysdeps/unix/sysv/linux/raise.c:56
56 ../nptl/sysdeps/unix/sysv/linux/raise.c: No such file or directory.
The nice thing about this problem is that it is consistently reproducible.
Any advice?
Chad
