#2912: GHCi bug: bus error when executing some gsl-random core
----------------------+-----------------------------------------------------
Reporter: fdeweerdt | Owner:
Type: bug | Status: new
Priority: normal | Component: GHCi
Version: 6.10.1 | Severity: normal
Keywords: | Testcase:
Os: Linux | Architecture: x86_64 (amd64)
----------------------+-----------------------------------------------------
When compiling this simple program, the resulting executable runs fine,
while running it under ghci causes a crash.
It's gsl-random related obviously, but the difference in behaviour between
plain ghc and ghci is somewhat odd.
