Since util-linux@3ab9e69 topology_set_value() is taking a unsigned long long value, but writing it into a struct with unsigned long fields. On 32 bit systems this results in corrupting the structure, as the two types are 8 and 4 bytes respectively. Signed-off-by: Alexander Kanavin <[email protected]>

Hmm... nice bug. I'm unsure if using 64-bit numbers everywhere is a good solution if the library API returns these numbers as "unsigned long" in many cases. It would be better to have topology_set_value64() and topology_set_value() to work wilt proper types from the beginning. Alternative bugfix: #2435 ;-) |

I'd also say it would be better to avoid using memcpy() so that compilers can do type checks, but I'm not sure if the code can be reworked easily that way. Thanks for the fix. |

Yes, memcpy() is pretty aggressive there, but it allows us to use one function for an arbitrary struct member by offsetoff(). |

Closing, fixed by #2435 |
