Hi:
A core file is generated by a tomcat server running JNI code.
Almost every 9 days it crashes at the same place. The $eip does not
point to .text section, but @plt section. The code breaks at writen@plt, so I don't have $ebp+0x4 point to the caller. I don't have clue as to
which line caused the crash. Is it a problem related with GCC compiler?
It
is not a compilation bug.
