Windows Color Management Library icm32.dll Crash

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.

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.
