----------------------------------+-----------------------------------------
Reporter: anish | Owner: simonmar
Type: bug | Status: new
Priority: high | Milestone: 6.10.2
Component: Runtime System | Version: 6.10.1
Severity: normal | Resolution:
Keywords: garbage collector | Difficulty: Unknown
Testcase: | Os: Unknown/Multiple
Architecture: x86_64 (amd64) |

Comment (by atze):
I have the same problem on AMD64, I have written a ray tracer in parallel
and with -N(2-8) (university computer, 8 cores) the program crashes every
time with a segmentation fault. -g1 fixes the problem but the program ran
much faster with parallel garbage collection :( Source code is available
if anyone wants it for testing purposes(post request here). Please fix
this, parallel garbage collection gives major speed increases! Thanks, ghc
and haskell are great.
