--- Comment #11 from henric at bergenwall dot com --- I have noted that the compilation works with any 2 out of the 3 gcc-flags! > gcc -finstrument-functions -ffixed-ebp a.c -> successfully compiles! > gcc -m32 -ffixed-ebp a.c -> successfully compiles! > gcc -m32 -finstrument-functions a.c -> successfully compiles! > gcc -m32 -finstrument-functions -ffixed-ebp a.c -> fails with internal error Given that -ffixed-ebp works individually with both -finstrument-functions and -m32, but not together, maybe it is tricky to error out on -ffixed-ebp, not destroying something that already works? Btw, in the company that I work for (>100.000 employees worldwide), we have legacy code that relies on -ffixed-ebp, so please don't be too aggressive when if you decide to error out on compilation with -ffixed-ebp.
