Apache 2.4: Segmentation fault with wrong reference from ap_get_module_config

[shiva prasad <s....@gmail.com>]

Hello All,

OS: RHEL 6 64 bit machine.

Getting segmentation fault with the wrong reference pointer from
ap_get_module_config.

here while creating the ga_vs_config for module config in the code
below(vs_config apr_palloc (p, s), it's returning the address 0x8477930,
but while getting the reference from ap_get_module_config (vs_config =
(ga_vs_config *)ap_get_module_config), it's returning 0x2009 and causing
segmentation fault while assigning vsid to it (vs_config->vsid = vsid).

Note: The issue is specific to 32 bit webserver on 64 bit machine, the same
is working fine with 64 bit apache 2.4 webserver.

can you please advice on the same.
