Make is seg faulting

Problem:
Make seg faults on

Signal 11
make: *** [gen/ptypes.cc] Error 139

ptypes.cc is a generated piece of code during compile. Because it somehow segs out, it never finishes writing the file. On subsequent makes, I get Error 1, due to the incomplete file not being able to generate the *.o file.

• first search for #ifndef instead of #ifdef...no problems.
  
• replacing changed files with original 2.27 files and recompile...success.
  
• put back changed files without defining MIT_uAMPS and added $(OBJ_MIT) to the end of $(OBJ) in Makefile.in and recompile...success
  
• ./validate wireless-test...success
  
• complete recompile...success
  
• #define MIT_uAMPS and recompile...failed
  

Semi-Fix:
The problem was because I uncommented #ifdef MIT_uAMPS in packet.h to bypass a compile error, and it ended up seg faulting. Man. A day wasted. See next post for real problem
