Some strange i64 behavior with arm 32bit. (Raspberry Pi)
Hi Tim,
thanks for the swift response!
@debug is defined in the same module, which makes this all the more confusing.

target triple = "armv6kz--linux-gnueabihf"
from the ghc produced module:
target datalayout =

If you are then curious how ARM-specific StgRun implementation looks,
then here it is:

#if defined(__thumb__)
#define THUMB_FUNC ".thumb\n\t.thumb_func\n\t"
#else
#define THUMB_FUNC
#endif
