USB isr breaks interrupt vector in STM32L1

Hi everyone,

I'm using the STM32L151C6

I have a program, running well, debugging with the ST-Link on IAR.

My problem is that as soon as I branch the USB_LP_IRQHandler IRQ to an existing function ( USB_Istr() ) in the startup_stm32l1xx_md.s file, the interrupt vector seems completely broken. It means I can't even debug, as the RESET handler is broken.

I have no idea how to debug this ..

Thanks for help !
