A couple possibilities here...

Is the shared library in RAM or ROM (e.g. are you using the SPT1500 tools to add it to a ROM image)?

Are you certain SysLibLoad and SysLibRemove are BOTH returning zero (no error)?

Take a peek at GSysLibTableP after you SysLibLoad and see if your library's SysLibTblEntryPtr->codeRscH is non-zero. If it's zero, SysLibInstall failed (perhaps in the library's install handler).

Also, are you running any hacks or patches to the SysLibXXX routines that could be affecting this?
