#3961: -O results in incorrect behavior on Mac OS X
-------------------------+--------------------------------------------------
Reporter: RichardG | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.12.1 | Keywords:
Os: MacOS X | Testcase:
Architecture: x86 | Failure: Incorrect result at runtime
-------------------------+--------------------------------------------------
Changes (by RichardG):
* cc: richa...@… (added)
* failure: None/Unknown => Incorrect result at runtime
Comment:
Further experimentation has shown the behavior differs when the {{{-O}}}
flag is used. I.e.,
{{{
ghc --make -i.:tests -cpp -DBASE4 tests/HUnitTest98.lhs
}}}
has the correct behavior but
{{{
ghc --make -i.:tests -cpp -DBASE4 -O tests/HUnitTest98.lhs
}}}
does not.
The severity of this issue is compounded by the fact that Cabal uses the
{{{-O}}} flag by default.
