I suspect there are still similar instances lurking, as I'm still seeing failures when running under QEMU, but this at least fixes the issue that was reported to us. Closes: https://bugs.gentoo.org/950017 Signed-off-by: James Le Cuirot <chewi@gentoo.org>

Subject: [PATCH] Fix Issue #768: Replace calls to ioFormatTest() in pngio_reg
|
|
|
|
* James Le Cuirot found a problem when ioformats_reg and pngio_reg
|
|
run in parallel because they both call ioFormatTest() and can
|
|
overwrite each other's output.
|
|
* Add a file-writing function in pngio_reg to do this properly, so
|
|
only ioformats_reg calls ioFormatTest().
