I have built couple of libraries and one application that uses these libraries using RVDS(used EABI technique). I have 
created the QNX executable using GNU linker available with momentics. The final executable crashes at some swich case 
with SIGSEGV in 'memset' library call.

If I comment all the 'memset' calls in the project then it runs for a while and then crashes with SIGSEGV

1. What could be the reason for it to crash in memset and how to resolve this ?
2. Even if I remove the memset it crashes in the switch case(same project created in momentics is running fine and hence
 I am sure there is no problem in the code), what could be the reason and how exactly I can debug this kind of binary ?
3. Is there any wrapper available in QNX to use RVDS ?
