[Haskell-cafe] SIGSEGV in yieldCapability ()

Hi. What would be the reason for Program received signal SIGSEGV, Segmentation fault. 0x00000000006071de in yieldCapability () (gdb) where #0 0x00000000006071de in yieldCapability () #1 0x000000000060bc6b in schedule () #2 0x0000000000609294 in real_main () #3 0x000000000060938d in hs_main () #4 0x00007ffff6b07eff in __libc_start_main () from /lib/x86_64-linux-gnu/libc.so.6 #5 0x000000000040a589 in _start () this happens in a program compiled with ghc-7.0.3 (and also, with ghc-6.12.3), running with +RTS -N on i7-920, ubuntu 11 (kernel 2.6.38-8) Could this simply mean "heap exhausted"? Thanks - J.W.
