The following examples illustrate some of the bugs I've encountered with 5.0a to date. Bug 1: 5.0a treats 0.0 as a char in the presence of float prototypes. Example: void foo( float null ) { } main(void) { foo( 0.0 ) ; } Aztec C Version 5.0a Jan 9 1990 7:57:19 Copyright 1989 by Manx Software Systems, Inc. clr.s -(sp) ^ File TMPA341.TMP; Line 16 # Opcode extension size did not match. 1 errors Bug 2: Prototypes are not generated correctly for functions taking array, or pointer to array arguments. Example: void foo1( char (*array)[3][2] ) { } void foo2(array) char (*array)[3][2] ; { } The above program, test.c, when compiled with -qp produces: void foo1(char array[2][3]*); void foo2(char array[2][3]*); Bug 3 (example superfluous): -wq logs only the first 25 (approximately) errors to AztecC.err. Additional errors are not logged, even when -ww is used. Tracking down these bugs takes time. Reporting the bugs in a general sense is much easier. In this spirit I've encountered the following additional bug. Bug 4 (sans example): _stkchk (via the -bd option) will occasionally corrupt the instruction immediately following its invocation (i.e. immediately following jsr __stkchk). Bug 5 (suspected, but not confirmed): sizeof(int) may not be working correctly. I *suspect* that sizeof(int) does not know whether 16 bit or 32 bit ints are being used, although I *have not* confirmed this. I rewrote the code using sizeof() and my problem disappeared. Mike, please keep me informed of the progress in correcting the above-mentioned bugs. In the past, compiler upgrades have been clandestine. Not once was I notified of an upgrade or a bug fix. In addition to these bugs, I have noticed that SDB bogs down when displaying source from lengthy source modules. SDB is a pain to use when working on modules longer than about 1000 lines of code. Forgive me if I seem blunt in my criticism of 5.0a. I realize that much has changed since 3.6 and that errors can be expected. If Manx supports 5.0a with courtesy, and corrects bugs promptly – if it offers
