#4914: FPU initialization required again
---------------------------------+------------------------------------------
Reporter: aruiz | Owner: simonmar
Type: bug | Status: new
Priority: high | Milestone: 7.2.1
Component: Compiler (NCG) | Version: 7.0.1
Keywords: | Testcase:
Blockedby: | Difficulty:
Os: Unknown/Multiple | Blocking:
Architecture: x86 | Failure: Incorrect result at runtime
---------------------------------+------------------------------------------
Comment(by aruiz):
It is strange, I can reproduce it in different x86 computers... Also, I am
now running all my programs based on hmatrix with the stack check and it
triggers frequently and reproducibly in some of them. But they are not
useful testcases because they have too many dependencies.
I don't want you to waste more time in this, but when I run
{{{
$ cabal clean
$ cabal install -f-vector -f-binary -fdebugfpu -fdebugnan
$ cabal test
}}}
I get something like [http://dis.um.es/~alberto/test.log this]. Don't you
get any error?
They are probably not very useful, but the executables built from bug.hs
with and without optimization are here: [http://dis.um.es/~alberto/bug1
bug1] [http://dis.um.es/~alberto/bug2 bug2].
