Bug: pattern length will visit illegal address in hs_compile_lit_multi

[ppx-ppx]

in function addLitExpression: // Ensure that our pattern isn't too long (in characters). if (strlen(expression) > cc.grey.limitPatternLength) { throw CompileError("Pattern length exceeds limit."); } the literal pattern maybe not ended with '\0', so strlen(expression) will visit the illegal address. maybe "strlen(expression) " should change to expLength which is user defined.

please check this bug
