Comment:
gcc is updated, but with:
{{{
hunk ./rts/Task.h 236
-#if defined(linux_HOST_OS) && \
- (defined(i386_HOST_ARCH) || defined(x86_64_HOST_ARCH))
+#if defined(mingw32_HOST_OS) || \
+ (defined(linux_HOST_OS) && \
+ (defined(i386_HOST_ARCH) || defined(x86_64_HOST_ARCH)))
#define MYTASK_USE_TLV
extern __thread Task *my_task;
}}}
I get:
{{{
$ cat q.hs
main = putStrLn "Foo"
$ inplace/bin/ghc-stage1 --make q -threaded
[1 of 1] Compiling Main ( q.hs, q.o )
Linking q.exe ...
$ ./q
Segmentation fault/access violation in generated code
}}}
and when linked with `-debug` too:
{{{

#11 0x00401570 in main ()
}}}
This isn't a regression, so I don't expect to dig deeper before the next
major release.
