Hi, I'm running helgrind against our code base and see this report. I once again cannot include all the code due to its proprietary and disclosed nature. Possible data race during write of size 8 at 0x58EEC60 by thread #1 Locks held: none at 0x4A87603: ... by 0xE818EB4: ... by 0xE816B04: ... by 0xE816ABE: ... by 0xDD80701: ... by 0xDD80701: ... by 0xDD1FF8C: ... by 0x42503E: ... by 0x4263B0: ... by 0x4267E6: ... Address 0x58eec60 is 160 bytes inside a block of size 408 alloc'd at 0x484BF58: operator new(unsigned long) (vg_replace_malloc.c:487) by 0xE816395: ... by 0xE8143DC: ... by 0xE8143DC: ... by 0x4A64C49: ... by 0xDD7427A: ... by 0xDD7E472: ... by 0xDD7E58E: ... by 0xDD1FF8C: ... by 0x42503E: ... by 0x4263B0: ... by 0x4267E6: ... Block was alloc'd by thread #1 I'm a bit confused as to how this can be a data race if there's only the main thread involved. Could this be a false positive or how do I read this report correctly? Thanks, Thomas |
