I made application using C++ in Linux in my computer ( 32 bit ). Once upon a time, a user installed it in 64 bit system. He tried to run it. Segmentation fault. No error message. No warning message. But he told me that my application runs fine in his 32 bit system.
I don't have 64 bit system. So maybe you all who has experience porting c++ application from 32 bit to 64 bit could give me a hint where do I start to solve this problem.... I use thread anyway.
