• odesaint June 22, 2009 10:35 AM PDT    vtdpview 64 bits segmentation fault Hi, I have the following problem when the  vtdpview load the sampling data: ... 18:05:05.546 Processing module 127 / 127  (mylib.so)                         Segmentation fault It seems the problem append when It analyses 'mylib.so' which is generated by my software. If I remove this library and relaunch vtdpview , there is no problem (vtdpview doesn't find this module anb bypass it ). Mylib.so is compiled from assembly code (with as GNU assembler 2.17) and link with gcc 4.0.2. I'm using 'Intel(R) Performance Tuning Utility version 3.2 Update 1 build 824'  on 64 bits machine (Xeon  E5430). I have no problem on 32 bits machine. Any ideas ? I don't know if you can help me ...

Olivier You might try building your shared object with the intel compiler..I would expect it to be able to take the asm directly..avoiding the two step build you do now Konstantin Lupach (Intel) July 7, 2009 8:53 AM PDT Rate   #2 Reply To #1 Re: vtdpview 64 bits segmentation fault If you really have no issues on 32-bit OS you can try to analyze the experiment there.  Copy the experiment (exp) and needed (exp/all/*.so) binaries (for example only this one to understand whether it helps). Try to convert it: vtdpview exp -c. If you still have problems try: disasmtool <binary>. In case it also crashes and the binary is not anyone's secret share it with us. In case disasmtool does not crash then share with us the experiment directory and problematic binary. It is always encouraged to mimize the amount of provided data. K
