Comment (by thorkilnaur):
The RTS, changed as indicated in the attached patch, has produced the
slightly extended log which is also attached. The log covers a run that
reports the memory leak, followed by a run that succeeds. A diff -C 1 of
the two runs contains
{{{
***************
*** 409,411 ****
allocGroup(1102,4) -> 0x1500f40 (block split)
! 280a600: starting GC
memInventory:
--- 410,416 ----
allocGroup(1102,4) -> 0x1500f40 (block split)
! freeGroup(0x1500f40,4)
! free block list:
! group at 0x1503000, length 123 blocks
! Memory leak?
! a000ed88: starting GC
memInventory:
***************
}}}
which confirms that the garbage collector is called between the alloc and
free in {{{hs_add_root}}}.
Best regards
Thorkil
