did you use the script in the toolchain directory in paparazzi svn ?
if yes, this is the version where I disabled the calls to assert_param
in libstm32  - on the current package ( 1.0.0-3 ) assert param is an
empty function call ( the function is defined in
sw/airborne/stm32/stm32_vector_table.c ). It doesn't do any bad thing
execpt slow the program alot. I2C is very sensitive to timing issue (
I still need to improve that ). I think this is what is causing your
problems.

I'm not familiar with eclipse, but I have the same behaviour when
using gdb from the command line. I don't know if there's a way to
"skip" that - if you don't care about interrupts during your
particular session of debug, maybe you could just disable them by
using gdb to write to the register
