I'm not sure if I should hate libsieve, flex or both, but this error message is horrible. I had no idea what it meant before looking at the sources. The code that produces it is in src/libsieve/sieve-lex.c:
while ( (result = fread(buf, 1, max_size, yyin))==0 && ferror(yyin)) \
{ \
if( errno != EINTR) \
{ \
YY_FATAL_ERROR( "input in flex scanner failed" ); \
break; \
} \So fread() fails, but it doesn't bother telling why. You could change the YY_FATAL_ERROR() to something like:
fprintf(stderr, "input in flex scanner failed: %s", strerror(errno));
That could give additional information. Although I've no idea why fread() would fail here.
