Hi everyone,
I'm Edward-san, a contributor of cppcheck (link:
https://github.com/danmar/cppcheck ) and I noticed a strange thing when
I was compiling it with some particular flags.
It happens with gcc 4.5.2 (the supplied one from Linux Mint 11 packages)
and in (the compiled-by-me) gcc 4.7.1 (I had a problem with cloog not
being recognized even with the correct version, but it's another matter).
Download the source here:
https://github.com/danmar/cppcheck/zipball/master and unzip it somewhere.
In the 'trunk' directory, write: "make lib/check64bit.o
'CXXFLAGS=-Winline -O'.
g++ will output those messages:
g++ -Winline -O -Ilib -c -o lib/check64bit.o lib/check64bit.cpp

but in lib/check64bit.cpp/h there's no 'inline' keyword near the
destructors (there's a 'inline' near 'Check::Check' in lib/check.h:148
but doesn't change anything when I remove the keyword). Maybe I don't
know something about this... if it's not a false positive, what would it
be the fix to this?
