Hi guys,

     I'm currently coding a plugin which needs to hook a virtual
function in CBasePlayer. The thing is, it works perfectly without any
issue under windows, but when I try the same code under linux all
hooking/callclass related macros cause a protection fault.

     I traced the crash to the following lines in this function:

bool CSourceHookImpl::AddHook(Plugin plug, void *iface, int
thisptr_offs, HookManagerPubFunc myHookMan, ISHDelegate *handler, bool
post)

                  // Tell it to store the pointer if it's not already activ=
e
                     if (hookman->vfnptrs.empty())
                             hookman->func(HA_Register, &(*hookman));

    XXX Crash here! XXX void **cur_vtptr =3D *reinterpret_cast<void***>(
                             reinterpret_cast<char*>(adjustediface) +
tmp.vtbl_offs);
                     void *cur_vfnptr =3D
reinterpret_cast<void*>(cur_vtptr + tmp.vtbl_idx);

Here are the flags I use during compilating/linking:

ARCH_CFLAGS=3D-O3 -fno-rtti -funroll-loops -s -pipe

BASE_CFLAGS=3D-fpermissive -D_LINUX -DNDEBUG -Dstricmp=3Dstrcasecmp
-D_stricmp=3Dstrcasecmp -D_strnicmp=3Dstrncasecmp -Dstrnicmp=3Dstrncasecmp
-D_snprintf=3Dsnprintf -D_vsnprintf=3Dvsnprintf -D_alloca=3Dalloca
-Dstrcmpi=3Dstrcasecmp -fPIC

        Any ideas ? Remember that the whole thing works fine under windows.=

                    Thanks in advance,
