bug with profiling things with "strange" filename
if you compile a program -p -auto-all with ghc and the name you give the exectuable contains iether a "." or a "-" (and possibly other things) it will core dump when executed (at least on sparc solaris), or so it seems, under 5.04. has anyone else had this problem? -- Hal Daume III "Computer science is no more about computers | hdaume@isi.edu than astronomy is about telescopes." -Dijkstra | www.isi.edu/~hdaume
Hi Hal.
5.04 profiled executables (-prof -auto-all) on Windows just crash on takeoff
with or without a dot in their name (ie even without a .exe extension).
This is substantially different to the behaviour of HEAD a few days before
release of 5.04, which only crashed when fed heap profiling arguments.
Cheers

The profiling crashes on the win32 side are due to a mangler
problem, causing all kinds of interesting side effects at run-time.
I've got a fix in the works, but before committing I want to spend
some more time understanding why 'gcc' insist on laying out
(and aligning) the profiling-related data structures the way it does.
