Issue created May 24, 2011 by waldmann@imn.htwk-leipzig.de@trac-waldmann

SIGSEGV in yieldCapability ()

the following 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)

Program received signal SIGSEGV, Segmentation fault.
0x00000000006071de in yieldCapability ()
(gdb) where

cf. http://thread.gmane.org/gmane.comp.lang.haskell.cafe/89244

My program uses STM and FFI. I am working on boiling down a test case. I open this ticket to perhaps get some directions.
