- A Note on a Bug in MrC[pp]
-
- After the preparation of the current Developer CD, a serious bug
- has been identified in the 4.1.0d2 prerelease versions of the MrC[pp]
- compilers. This bug appears only under the -opt speed and
- -opt size options and results in incorrect code involving conditional
- statements. The bug may not manifest itself very often: it did not
- appear in the compiler tests used to validate MrC[pp], but did appear in
- building a new version of the standard C library (see below). The bug has
- already been fixed, but not in time to replace the current versions of
- MrC[pp] on this release. New versions of the MrC[pp] compilers and
- associated libraries will be appearing on the MPW web site shortly.
-
- The bug found in the StdCLib 3.5d7 library is in the %g format specifier to
- the printf family of functions in <stdio.h>. According to the C Standard,
- in %g format, "trailing zeros are removed from the fractional portion of
- the result." This step is being skipped in this library. This behavior will
- be fixed in the next release.
