#3831: GHC uses too much memory compiling terminfo
---------------------------------+------------------------------------------
Reporter: igloo | Owner:
Type: bug | Status: new
Priority: high | Milestone: 6.12.2
Component: Compiler | Version: 6.12.1
Keywords: | Difficulty:
Os: Unknown/Multiple | Testcase:
Architecture: Unknown/Multiple | Failure: Compile-time performance bug
---------------------------------+------------------------------------------
On x86/Linux, with this `mk/build.mk`:
{{{
GhcLibWays = v p dyn
SRC_HC_OPTS = -O -H64m -Rghc-timing
GhcStage1HcOpts = -O -fasm
GhcStage2HcOpts = -O2 -fasm
GhcHcOpts = -Rghc-timing
GhcLibHcOpts = -O2 -XGenerics
#SplitObjs = YES
SplitObjs = NO
HADDOCK_DOCS = NO
BUILD_DOCBOOK_HTML = NO
BUILD_DOCBOOK_PS = NO
BUILD_DOCBOOK_PDF = NO
#
-----------------------------------------------------------------------------
# Other settings that might be useful
# profiled RTS
#GhcRtsCcOpts = -pg -g
# Optimised/profiled RTS
#GhcRtsCcOpts = -O2 -pg
#GhcRtsWithFrontPanel = YES
#SRC_HC_OPTS += `gtk-config --libs`
# NoFib settings
NoFibWays =
STRIP=:
}}}
and these commands:
{{{
$ sh boot
$ ./configure --prefix=/opt/ghc-6.13
$ make
}}}
and a 1GB memory limit (`ulimit -v 1024000`), the build fails with:
{{{
