I'll put this in another thread, apologies if this bothers anyone. I explained that my application crashes without error messages under certain conditions (when I ask it to provide reports about stock evolution over several periods).
The app source contains logging statements, and I just added some to try
and figure out where it is crashing.
The relevant piece of code is in attachment code.c (not inlined in this
mail because all the lines wrap), the logfile is in log.txt .
The application is crashing in a line that basically prints log info.
I've written a couple of lines before it printing out all the info that
get printed in the offending statement. The separate print statements
work, the combined one crashes the application.
This is also what happens under gdb : the application crashes when in
the line
Log(STATUS_LOG, "Value Change %d - %d -> [%s]\r\n",
value, prevValue, valval);
The output of a gdb session is also attached.
Bright (and other) ideas are most welcome.
