Hi All,

I have a very strange problem, I had developed a application which would playback the contents from the https server.
In this issue, when I play the content URL Server A it leads below crash, but if I a play from Server B URL it plays properly. Both Server A and Server B are HTTPS servers and files are different.

Exception!
signal: Illegal instruction
reason: kernel

Verbose prints for Server A is here
* Connected to Server A (xxx.xxx.xxx.xxx) port 443 (#0)
* successfully set certificate verify locations:
* CAfile: /etc/ssl/certs/ca-certificates.crt
  CApath: none
* SSL connection using RC4-SHA
* Server certificate:
* subject: C=US; ST=Arizona; L=Tempe; O=Limelight Networks, LLC; CN=*.hs.llnwd.net
* start date: 2009-06-15 14:39:34 GMT
* expire date: 2012-09-16 06:17:48 GMT
* issuer: C=US; O=Equifax; OU=Equifax Secure Certificate Authority
* SSL certificate verify result: certificate is not yet valid (9), continuing anyway.

If I delete /etc/ssl/certs/ca-certificate.crt from the archive, then the application would play from the Server A.
I don't understand why deleting ca certificates from /etc/ssl/certs/ca-certificate.crt would playback the file.

Any hints on this issue is highly appreciated.
