Losing interrupt when returning from another interrupt

When returning from PWM0 interupt (priority 3) we get a negative flank on pin 5.8 (EXTIT06) This should generate an EXTIT06 interrupt (priority 15), but instead this interrupt is lost (never serviced).

Seems that the assembler code returning from interrupt (clearing pending bits etc.)does not handle this situation.

Any advice on this topic?

Hello,

could you check if you have configured the EXTIT06 line and the EIC as well?
