It did, so exceptions do seem to be working now. I've uploaded an updated bootstrap compiler for armel and two new patches. The patch kit now is: gcc-4.4.1-arm-eabi-ada-1.patch: initial patch gcc-4.4.1-arm-eabi-ada-2.patch: update copyright and licence text gcc-4.4.1-arm-eabi-ada-3.patch: make SJLJ exceptions work, fix a warning gcc-4.4.1-arm-eabi-ada-4.patch: revert xsinfo.adb dont-use-exceptions kludge For those with a compiler based on the initial patch only, apply patches 2 and 3 first, rebuild, then apply patch 4. /Mikael
