#3664: Ghc eats tremendous heaps of RAM in -prof build (highlighting-kate)
-----------------------+----------------------------------------------------
Reporter: slyfox | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.12.1 RC1 | Severity: normal
Keywords: | Testcase:
Os: Linux | Architecture: x86_64 (amd64)
-----------------------+----------------------------------------------------
Tried to build '''highlighting-kate-0.2.5''' from hackage with ghc-6.12rc1
and could not wait build result. Ghc ate 2.5BG of ram in 6 minutes, then I
stopped it as machine swapped horribly.
