I am facing Fatal Signal 11 .

My log function is into Native

Answer 1

The segmentation fault signal points to some type of memory problem and, taking into account that you set logMessage and tmpString to the same length and you're filling logMessage with several arguments plus the content in tmpString, as Peter states, is very possible that you're running into a buffer overflow.

Initially, logMessage's length should be: MAX_APPNAME_LEN + MAX_DEBUG_LEN + 4 + MAX_TIMESTAMP_LEN + MAX_MODULENAME_LEN + PATHLENGTH.
