[Mingw-users] Segmentation violation using recent CVS version of gprof -l on MinGW32 + fix

[K S. <sc...@fe...>]

Using the MinGW32 version of binutils (version 
binutils-2.13.90-20030111-1-src.tar.gz )
I get a segmentation violation using gprof -l <executable-name>.

This used to work with earlier gprof versions.

The problem seems to have to do with the call to sym_lookup with
address -1, which apparently on other platforms returns something 
like "<hicore>". However, on MiNGW32 this returns sentinel = 0,
which leads to a segmentation violation.

The patch: check for sentinel == 0, and if it is zero do not perform
the sentinel->addr correction. With this patch gprof seems to work
again. 

Attached is a fix. I do not read this list on a regular basis.
