Compiler/TMS320C6748: Incompatibility SYSBIOS 6.37 with CGT 8.3.35 compiler

Tool/software: TI C/C++ Compiler

Hello,

Is there some incompatibility for SYSBIOS 6.37 when using 7.2.24 and 8.3.35 CGT compilers? My project uses the libraries below but if I compile with 7.2.24 the project runs fine (has been used for 5 years already) but when compiled with 8.3.35 randomly crashes after anywhere between few minutes to few hours.

UIAPATH := /ti/uia_1_03_01_08
XDCPATH := /ti/xdctools_3_25_06_96
EDMA3 := /ti/edma3_lld_02_11_11_13
DSPLIB := /ti/dsplib_c674x_3_1_1_1
MATHLIB := /ti/mathlib_c674x_3_0_1_1
SYSBIOS := /ti/bios_6_37_05_35
XDAIS := /ti/xdais_7_21_01_07

Most common exceptions are:

ti.sysbios.heaps.HeapMem: line 371: assertion failure: A_invalidFree: Invalid free

I was looking with ROV and Exception module returns these:

Exception call stack,

Apparently ROV reports on BIOS module: "All ROV views have been run and no errors were encountered. In BIOS, this includes a check of the System stack usage and all Task stacks."

Best regards,
