We have encountered a crash in the Windows Color Management library (icm32.dll), in the icm32!LHCalc3toX_Di16_Do16_Lut8_G32 function, while trying to translate colors based on a malformed color profile file:

The issue reproduces on Windows 7. It is easiest to reproduce with PageHeap enabled. In order to reproduce the problem with the provided samples, it is necessary to use a dedicated program which loads the file, creates a color transform and translates some colors.

Attached are two color profiles which trigger the crash at two different offsets within the icm32!LHCalc3toX_Di16_Do16_Lut8_G32 function.
