Hi,
I have a mysterious problem with running a 2.2.6 binary (dynamically
linked) on a 3.1 box. The crazy thing is that it has worked flawlessly
before.
After doing a bit of development and compiling it again, I get
segfaults when I try to run it on the 3.1 box.
When I try it with an a.out gdb (ftp'ed from the 2.2.6 box) I get this:
> ./gdb web-ssql

(gdb) r -v
Starting program: /home/bowtie/web-ssql -v
reading register eip (#8): Bad address.
(gdb)
(3.1) ldd web-ssql:
> ldd web-ssql
web-ssql:
-lcrypt.2 => /usr/lib/aout/libcrypt.so.2.0 (0x200a3000)
-lm.2 => /usr/lib/aout/libm.so.2.0 (0x200b8000)
-lc.3 => /usr/lib/aout/libc.so.3.1 (0x200d2000)
(2.2.6) ldd web-ssql:
web-ssql:
-lcrypt.2 => /usr/lib/libcrypt.so.2.0 (0x200ab000)
-lm.2 => /usr/lib/libm.so.2.0 (0x200ae000)
-lc.3 => /usr/lib/libc.so.3.1 (0x200c8000)
When I link the binary statically it works ok, but unfortunately I
need it to be dynamically linked.
Does anyone recognize this behaviour? And even better knows whats
going on?
Regards,
Marc.
