Release 5.18

• Correct a problem with statement expressions in that the last statement inside was incorrectly evaluated twice.

• Alignment attribute is now properly obeyed on struct members.

• Attributes on a record declaration is now applied to all variables being defined in record declaration.

• Variable argument functions with the parameter before the ... passed in register could in some situations clobber the register.

• Volatile variables in a function that uses setjmp() would not always preserve an assignment to it.

• An incomplete array at the end of a struct record is now properly initialized.

• MEGA65: Correct a problem where conversion to a different pointed-to size of a 'far' or 'huge' pointer and using an index expression would result in incorrect index scaling.

• MEGA65: Correct an internal error (labeling failed) that could occur when pushing a variable (or part of variable) held on the zero page as a pushed parameter.

• 6502: Fix an internal error cannot hi (_Zp+N),y which could occur in combination with a 16-bit += operator.

• 6502: Format strings for printf and such no longer perform PETSCII conversion on format fields inside string literals when using the --string-literal option. Characters apart from the format fields are converted as before.

• 65816: Correct a problem where conversion to a different pointed-to size of a 'far' or 'huge' pointer and using an index expression would result in incorrect index scaling.

• 65816: Fixed a problem with adjusting a __far pointer with a negative constant index could cause incorrect address calculation.

• 65816: Testing a 32-bit value against zero would in some situations clobber the value.
