This is just heads up.
In last six month or so, quality of debugging info. generated by GCC
3.5 has regressed significantly (as per GDB test suite results).
According to Michael Chastain's test results
http://gcc.gnu.org/ml/gcc-testresults/2004-08/msg00833.html
http://www.shout.net/~mec/sunday/current/Non-PASS-gdb-6.2-suite-
HEAD.html
Use of GCC-3.5 results in 925 and 905 failures for STABS and DWARFS
format respectively. For the same version of GDB, however use of
GCC-3_4-branch results in 33 and 55 failures.
Above numbers are for i686-pc-linux-gnu. We are seeing similar (not
identical) numbers for powerpc-darwin-apple using different GDB
version. Right now we are seeing 859 failures for STABS, where as we
saw only 239 failures in mid March.
