[stunnel-users] core dump when running stunnel on Arm based board

Sun Dec 16 16:05:12 CET 2012

don't know, we were using stunnel 4.52 and openssl 1.0.0.the goal is to use stunnel 5.0.
right now i'm at the point, even if i move to stunnel 4.53, it starts crashing even without any arguments.it should just print the help message, has nothing to do with openssl.
thanks for your reply !

Hi, just a question : do you have an openssl lib matching your target platform ?with proper include files and libs accessible at compile time and run time ?Pierre

actually problem starts from 4.53.
1. build and run 4.52 is fine2. 4.53 crashes3. setup gdb, as long as i connect to target, it says cannot access memory 0.    after i set breakpoint at main() in stunnel.c, it get seg fault signal when i hit "continue" in gdb.
panic ...

Hi everyone, i'm new to this.
got a task to update stunnel from 4.52 to 5.00b1.
1. ./configure --host arm-none-linux-gnueabi --target   arm-none-linux-gnueabi --prefix=      i compared the makefile with the one in our 4.52 code base, same.
2. build with     make -C stunnel CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm
3. scp to ARM board, run without arugments, core dump.    (the line number might be different as i was putting printfs. but as long as it enters parse_commandline, it crashes)
    [New LWP 867]Cannot access memory at address 0x70797263(gdb) bt#0 parse_commandline (name=0xbefdce29 "/opt/ultra/config/stunnel.conf", parameter=0xbefdce48 "-version") at options.c:1940#1 0x0003ba04 in main_configure (arg1=0xbefdce29 "/opt/ultra/config/stunnel.conf", arg2=0xbefdce48 "-version") at stunnel.c:199#2 0x0003bd44 in main_unix (argv=<optimized out>, argc=<optimized out>)at stunnel.c:135#3 main (argc=3, argv=0xbefdcd24) at stunnel.c:110my question is, it crashed when just entering parse_commandline( ),the 2 arguments look fine to me.How could this happen ?Many thanks !
