Hi Everyone,
I built the latest iConv release tarball with -fsanitize=undefined and
then ran the self tests with 'make check'. It produced a few findings:
...
./check-stateless . CP874
./check-stateless . VISCII
viscii.h:127:56: runtime error: left shift of 1 by 31 places cannot be
represented in type 'int'
./check-stateless . TCVN
tcvn.h:220:56: runtime error: left shift of 1 by 31 places cannot be
represented in type 'int'
./check-stateful . TCVN
...
This is a fairly common finding.
Jeff
