#1943: round function causes cblas NaNs
---------------------------+------------------------------------------------
Reporter: SevenThunders | Owner:
Type: bug | Status: new
Priority: normal | Milestone:
Component: Compiler | Version: 6.8.1
Severity: critical | Keywords:
Testcase: | Architecture: x86
Os: Windows |
---------------------------+------------------------------------------------
After calling the round function, a call to an external C function causes
NaNs to appear in the calculation. The external C function in this case
is the BLAS function cblas_dgemm() from the atlas library. The cblas
library was compiled on a 32 bit windows XP machine. The same bug occurs
on my 64 bit dual core athlon under windows. I suspect the Atlas version
number was 3.7.33. I have enclosed the 32 bit atlas dll library I use and
the .bat script I used to compile the simple case. Please note this
example works just fine for ghc 6.6.1 which I also verified.
