#3282 Compiler Internal Error : Unimplemented conditional jump.
sdcc 4.1 and the current svn (r12073) bring up an internal compiler error for a seemingly simple piece of C code.

rm -f i2c.rel
sdcc --Werror --std-sdcc99 -mstm8 -c -o i2c.rel i2c.c

make: *** [Makefile:10: i2c.rel] Error 1
I'll attach the Makefile and i2c.c, both reduced to the absolute minimum that's needed to reproduce the bug. Simple changes to the C code, e.g. removing the num < 1 check or removing the num == 2 if clause or the I2C_DR = val[1]; make the compilation succeed.
This code compiles as-is with sdcc 3.8.
Thanks in advance for looking at this. Of course, I'm happy to do more testing to help tracking down the issue.
oops, the Makefile wasn't attached. I'll try again
Fixed in [r12685].
