Looks like this commit introduced the error, Is there a fix?

How did you build curl? Did you by any chance use cmake to do it?

[SukanyaHanumanthu]

Did the below as we applied a minor patch to multihandle.h

    make && \
    make test-full && \
    make install

[bagder]

but how did you generate the makefile?

[bagder]

When curl is built with cmake, it is not threadsafe see #8982 for pending work on that

[SukanyaHanumanthu]

Used GNUMake for the above and not cmake, is it a known incompatibility?

[bagder]

but before make you invoked configure or cmake surely?

[SukanyaHanumanthu]

• removed cmake which was part of the install script and tested which had no change in behaviour, just an unwanted line.
• correct about the configure part, which had the below lines before make test

        --disable-shared \
        --with-pic \
        --without-ssl \
        --without-zlib && \

Does this affect the test?

[bagder]

Well, now you're complicating this issue. I think you now see "no difference" because you didn't properly rebuild everything after you changed from cmake to configure. Also, do you really want --without-ssl ? It is very unusual.

The fix for the original issue you submitted has been proposed in #9142 though.

[SukanyaHanumanthu]

Thank you for the above, configure was present before/after removing the cmake (configure was always there), though cmake was installed on linux (removed now and tested), it was never used and had no influence, the code always used GNU Make only with configure.
