I'm having trouble with the curl executable but since this is a little
hairy, I'm posting to curl-library.

I just built from the latest code in CVS and I'm getting a segfault.

$ ./curl --version
curl 7.15.4-CVS (i686-pc-linux-gnu) libcurl/7.15.4-CVS OpenSSL/0.9.7a
zlib/1.1.4
Protocols: tftp ftp telnet dict ldap http file https ftps
Features: Debug Largefile NTLM SSL libz

Here's how I'm invoking curl:

$ ./curl -d mo=R -d y=1 -d m=5 http://localhost:8739/mapview/index.jsp

Removing any of the -d args makes it work. Changing the order of the
-args doesn't seem to change anything -- it still segfaults. Changing
the name of the param or value doesn't seem to change anything.

Changing the URL has an effect though. Wrapping it in quotes doesn't
make a difference but

./curl -d mo=R -d y=1 -d m=5 http://localhost:8739/mapvie

gives me a segfault and

./curl -d mo=R -d y=1 -d m=5 http://localhost:8739/mapvi

doesn't.

This also happens to me on 7.15.3

Here's some host info

$ uname -a
Linux <my hostname> 2.4.21-4.ELsmp #1 SMP Fri Oct 3 17:52:56 EDT 2003
i686 i686 i386 GNU/Linux

I configured with:

 ./configure --disable-shared --enable-debug --enable-maintainer-mode

This seems like the kind of thing that would have bitten people long
ago. Anyone see a build problem?

In case it helps:

$ ldd curl

        libcrypto.so.4 => /lib/libcrypto.so.4 (0xb74b1000)

        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0xb75eb000)

Finally, here's the stack trace:

Thanks much for your help.
