Hi Eric, To be onnest i have never use any debugging tool or whatever.
And i will see how far i come with the libsigsegv Eric Blake wrote:

Can you also send your config.log? It looks like three categories of errors; I'll reply with separately subject lines to make tracking the distinct issues easier. First, it looks like stack overflow detection is not working: | Checking ./stackovf.test | Can't reset stack limit - this may take a while... | Failure - m4 did not abort | Output from m4: | ... | FAIL: test-c-stack.sh Are you in a position to help debug this? The simplest test would be capturing the output of: $ u:/m4-1.4.11.34-9ecd/src/m4 --help | grep limit $ echo 'define(a,a(a))a' | u:/m4-1.4.11.34-9ecd/src/m4 $ echo $? checks/stackovf.test was supposed to do this, but it might still be buggy; at any rate, the output from the test looks like m4 exited without any output and with 0 exit status, even though it should have died from stack overflow. Maybe the process is being killed silently by the OS, similarly to how mingw behaves without libsigsegv? The --help output will show whether m4 is even attempting stack overflow detection (--nesting-limit default to 0) or giving up entirely due to no OS support (--nesting-limit default to 1024, as it is on mingw without libsigsegv). If you are familiar with gdb, it would also be nice to step through test-c-stack. It seems a bit odd that stack overflow failed (test-c-stack.sh invokes test-c-stack without arguments) but a forced SIGSEGV passed (test-c-stack2.sh invokes it with an argument). Also, it looks like you built without libsigsegv installed. Would you be willing to download libsigsegv (2.5 is the latest release, although there are some patches in CVS that have not yet been released, necessary for correct operation on some platforms such as OpenBSD), report how it fares with 'make check', and also try rebuilding m4 with libsigsegv? - -- Don't work too hard, make some time for fun as well!
