Should I be > worried? My GCC version is 3.4.3, in case that matters. Btw, I see warnings on GNU/Linux as well, with GCC 4.0.3 and Binutils 2.16.91: During symbol reading, incomplete CFI data; unspecified registers (e.g., rax) at 0x444d44. During symbol reading, DW_AT_type missing from DW_TAG_subrange_type. This is when debugging a recent snapshot of GDB with itself. Does anyone else see this? Are the compiler and/or Binutils installed on that system (fencepost.gnu.org) too old?
