Problem LibJPEG jcdctmgr.c

several days ago I'm trying to encode a BMP image to jpeg, when I do debbug I see that in the jcdctmgr.c file, in the GLOBAL (void) function jinit_forward_dct (j_compress_ptr cinfo)  function, an error occurs at this point fdct = (my_fdct_ptr)     (* cinfo-> mem-> alloc_small) ((j_common_ptr) cinfo, JPOOL_IMAGE, SIZEOF (my_fdct_controller)); and it sends me to void HardFault_Handler (void) in the file stm32f4xxit.c, I think it's strange because LibJPEG is a set of independent libraries, does anyone have any idea how to solve this problem?


I am working with the STM32F446VE, STM32CubeMX version 4.21 and IAR, with a simple board made by my own, it has a SD card, and the fat files works fine.
