Catch over range lam0 in proj_etmerc.c
lam0 of inf caused a nan in the cast to int.
Picked +/-1000 for lam0 as a guess for what constitutes reduculously large values.
proj_etmerc.c:361:16: runtime error: nan is outside the range of representable values of type 'int'
Found with autofuzz: UndefinedBehaviorSanitizer: float-cast-overflow
