Re: [Valgrind-users] suppress warning repetition

[João M. S. S. <joa...@gm...>]

The problem is in:

char command[128];
sprintf(command, "first part of command %s second part of command", 
filename.c_str());

The string is larger than 128 bytes. But valgrind does not detect this? 
Am I missing something?

I forgot to mention, I'm using valgrind from SVN in an ARM machine.

I usually use the version from SVN since it has a lot of false positives 
corrected.

The log file shows 0 errors but a lot of:

==2346== Warning: invalid file descriptor 29541 in syscall read()

which make it difficult to interpret the results.

Should I report a bug and a suggestion upon this SVN version?
