Hi,
In the msys2 shell, I'm building gmp (with specific configure args) and then
mpfr.
But there are 3 crashing tests in the mpfr test suite for which I would like
to obtain a backtrace - but so far, all I'm getting is "No stack".
In the hope that someone might be able to see how I can improve on this
(non) result, here's exactly what I'm doing.
gmp-6.1.2 source and mpfr-4.0.0 source are in /c/scratch.
In /c/scratch/gmp-6.1.2 I run:
./configure disable-shared --enable-static --enable-assert CC="gcc -ggdb" &&
make && make check.
That works fine, the -ggdb is propagated throughout the build, even to the
compiling of the gmp test executables (all of which pass).
Then, in /c/scratch/mpfr-4.0.0 I run:
./configure
disable-shared --enable-static --with-gmp-build=/c/scratch/gmp-6.1.2 && make
&& make check
Again, the -ggdb flag (which mpfr inherits from gmp) is propagated
throughout the build, including the compiling of the mpfr test executables
(all of which pass except for the 3 crashing test programs).
The first crashing test is tests/tfprintf.exe, so I 'cd' to the tests
directory and run:

And it's the same for the other 2 crashing test scripts (tprintf.exe and
tsprint.exe).
Is there something I can do here to obtain a useful backtrace ?
Cheers,
Rob
