#1357: trouble using newForeignPtrEnv
-----------------------+----------------------------------------------------
Reporter: Frederik | Owner:
Type: bug | Status: new
Priority: normal | Milestone:
Component: Compiler | Version: 6.6
Severity: normal | Keywords:
Difficulty: Unknown | Os: Unknown
Testcase: | Architecture: Unknown
-----------------------+----------------------------------------------------
I am attaching files to hopefully reproduce a problem I am having. I have
not upgraded to 6.6.1 yet so let me know if it has been fixed.
$ touch fpenv_c.c fpenv.hs && cc -g -Wall -c fpenv_c.c && ghc -fasm --make
fpenv.hs fpenv_c.o -lc
[1 of 1] Compiling Main ( fpenv.hs, fpenv.o )
Linking fpenv ...
$ ./fpenv
(x,xFP)=(0x08090628,0x08090628)
fin_test: env=0xa7900040, p=0x808e00c
zsh: segmentation fault ./fpenv
[139]$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 6.6.20070420
Running in valgrind shows:
...
fin_test: env=0x437c008, p=0x1
==12777==
==12777== Jump to the invalid address stated on the next line
==12777== at 0x1F: ???
==12777== Address 0x1F is not stack'd, malloc'd or (recently) free'd
I think this is when fin_test exits. I am experiencing this problem in a
much larger program, so I wrote this test case to figure out what is going
wrong. Am I using the newForeignPtrEnv API incorrectly?
